AEM Cold Air Intake System for 1.9L VW Jetta & Golf TDI – Install Videos

May 2, 2012

In this two part installation video, we show you how to take the stock intake filter from your 1.9L VW Jetta or Golf TDI and replace it with an AEM Cold Air Intake.  Specifically, one that moves your intake filter out of the engine compartment and down into the wheel well, making it a true diesel cold air intake. Relocating the filter out of the stock location allows you to get cooler air inlet temperatures, and improved diesel performance is all about a better combustion event, achievable with a cooler, denser, more oxygen-rich air intake charge.

AEM diesel intakes come with DryFlow filters that are washable and reusable, and do not need to be oiled after cleanings, making them convenient to maintain.

One thing to be aware of though when moving the air filter down into the wheel well – if you drive through water deep enough to suck water in through the filter, you’ll destroy your engine.  To overcome this obstacle, the diesel intake engineers at AEM offer a bypass valve.  This bypass valve shuts down induction through the filter whenever the filter becomes submerged.  Intake air is rerouted instead through the external diaphragm of the bypass valve.

We also recommend you add an AEM pre-filter to keep normal splashes of mud and water from saturating your intake filter.   The pre-filter is made of a durable micro-screen material and has been pre-treated with AEM’s proprietary hydrophobic process.  The combination of the pre-filter and the bypass valve gives you the protection you need.  Here’s a look at the pre-filter.

AFE Stage 2 SI Cold Air Intake Install Video: 2008 Ford 6.4L Powerstroke

November 11, 2011

Parley’s Diesel Performance carries all the top brands of diesel intakes and diesel cold air filters like those from Advanced Flow Engineering, or AFE as they are commonly called.  Over the past few years AFE diesel intakes have become recognized as some of the best cold air intakes available.   Many AFE cold air intakes have an open or exposed filter element, but for certain vehicle applications AFE has designed an intake system with a fully enclosed filter.  A good example would be the sealed Ford diesel cold air intake for the 6.4L Powerstroke trucks built from 2008 through 2010.

AFE’s Stage 2 Si ( sealed intake) for the 6.4L Powerstroke shows signficant improvements in airflow and real power increases.  Dyno testing of the AFE Stage 2 Intake shows gains of 28 Horsepower and 54 ft. lbs. of Torque at 2000 RPM.  That’s a pretty significant increase in power to a truck that already makes big numbers from just adding a cold air intake system.  The increase in airflow is also improved by 41% over the stock airbox, pushing an additional 65 CFM (stock is about 160 CFM).

The AFE Stage 2 Si intakes also help maintain a factory appearance by utilizing a fully sealed commercial grade air box that replaces the entire OEM air box.  Part of what makes this particular Stage 2 Si unit so effective is the use of a built in ram-air scoop which forces more cold air into the filter area.  And last but not least, like with all true diesel performance intakes, adding a large, conical filter with pleated ridges increases the surface area of the filter, allowing for more air to be filtered more quickly.

Cummins Performance, the Best in the Biz

July 1, 2008

The Dodge Cummins diesel is known for its diesel fuel mileage and ability to be built up for power…. and known for its transmission for different reasons.  The Dodge Diesel trucks are the favorite of anyone that is looking for fuel economy in a diesel and doesn’t have a brand preference, because the dodge gets the best economy of them all.  Even at that, things are tight with the cost of diesel and the hard times in the economy.  There are some things that can be done to make it even more fuel efficient.

The first thing that anyone is going to do to make their Dodge Cummins diesel more efficient for fuel economy and power is install a Cummins diesel chip, programmer or module of some sort.  Cummins performance diesel chips, programmers, and modules all do essentially the same thing.  They alter “timing” or when the fuel is injected; “duration” or how long the injector is held open to release fuel; or “pressure” which slightly increases fuel line pressure to put more pressure up against the injector and get a better atomization of the fuel.  Most chips, programmers or modules use a combination of the methods to improve engine efficiency.  Most chips, programmers or modules give anywhere from 1 to 5 miles per gallon increase in fuel economy, dependant upon driving habits and the truck configuration itself.  The gains for the 5.9L Cummins engines are pretty consistent, however, the new 6.7L Cummins diesels are different.  They have a new emissions control system with a diesel particulate filter that hampers performance and fuel economy.  Most chips give these new trucks about 1 mpg better fuel economy.

Another way to increase efficiency and power are air intakes and larger diameter exhaust systems. Cummins diesel intakes generally give about 1 mpg and exhausts can be anywhere from 1 to 4 mpg.  If you do a chip, intake and exhaust all together, you actually get a little bit more out of each item.  The nice thing is that all the add-ons give more power and pay for themselves pretty quick in the added fuel savings.  The newer Dodge Cummins diesels don’t really need an exhaust upgrade since they come standard with a 4 inch diameter exhaust from the factory on the 2004.5 model and newer Dodge Cummins diesel trucks.  Performance diesel exhaust changes that can be made on the 6.7L trucks is very minimal due to all the sensors in that exhaust system.  It’s nice to know that we have alternatives though.

How To Increase Diesel Fuel Mileage!

March 27, 2008

As of late we are getting a lot of people asking how to increase diesel fuel mileage.  With diesel over $4.00 a gallon and expected to go well over $5.00 a gallon this summer its no wonder why people are wondering how they can increase diesel fuel mileage.   Here are the things we have found that work best to increase diesel fuel mileage:

Diesel Performance Chip: Using a diesel performance chip is one of the easiest ways to increase your diesel fuel mileage, usually with about ten minutes or so spent installing a “chip”, you can increase your fuel economy by 1-5 MPG.  Some companies have actually released chips dedicated to increasing diesel fuel mileage including the Edge Mileage Max, Hypertech Max Energy and Quadzilla Max Mileage.

Diesel Performance Intake: Usually if you have already added a chip the next best thing to help increase diesel fuel mileage.  Diesel performance intakes allow your engine to breathe easier, which will help increase diesel economy.  You will usually see a 1-4 MPG increase.  Some of the best known performance intake manufacturers are S&B Filters, AFE and Airaid.

Water Methanol Injection: Now most people would recommend going with an exhaust system for your third mod to increase fuel economy.  We have found that when it comes to bang for your buck, the Snow Performance Water Methanol Injection Kits lower exhaust gas tempratures more and increase diesel fuel mileage better than an exhaust system.

If you have any further questions on how to increase diesel fuel mileage please contact us.

Diesel Performance – Miracle or Snake Oil

March 6, 2008

There are so many products out there that just seem to be too good to be true and there are too many people out there that are more than willing to take advantage of another’s lack of knowledge.  There are also sooo many out there that are willing to play on peoples emotions; you know, the whole “You can have amazing results for practically nothing, and for only minutes a day at no cost to you”.  We’ve all heard it before.  So what makes diesel performance parts, like a chip, or a cold air intake, or an exhaust any different.  You might ask yourself, “Can adding something that small to my vehicle produce as great results as so many people tell me they do?”  Or will these items really pay for themselves in the form of increased diesel fuel mileage, and reduced wear and tear on my vehicle?  It is these questions about these products that I am going to address and at the same time educate, because knowledge is power my friends.

If you were to modify a gas engine for performance, you would be required to install a different camshaft, bore out the cylinders to increase displacement, install high compression pistons and heads, increase fuel intake capability by installing a larger carburetor or injection system, adding a turbo charger or supercharger, adding a chip, and enlarging the exhaust system.  But then you are still restricted by emission control systems.  On the other hand, diesel trucks and cars are mostly turbo charged, and they already run at a higher compression ratio.  Whereas on the gas vehicles you would have to make those changes.  If you were to make those changes to a gas engine you would truly have a ground pounding beast, but would lose every day driveability.  The diesels on the other hand, are nice to drive around even with considerable modification.  With a cold air intake, a diesel chip, more efficient injectors, and a more open exhaust system, the diesels are still a nice ride, but when you really give it the gas, all heck breaks loose.  There is enormous power without reducing driveability.

Because of the nature of diesel engines, they are designed from the factory to withstand much higher compression ratios than a gas engine.  The diesel fuel combusts when it is compressed to a certain point whether or not there is optimum air. By simply shooting more fuel into the combustion chamber you can make more power. When you then improve the air ratio & timing of the fuel — you can make dramatic power and also improve engine efficiency.  Gasoline requires a spark to ignite it & must have the appropriate mixture of air to burn properly.  Also, there is also a lot more energy in a given amount of diesel fuel than in an equal amount of gasoline.

Below is a break down of the most popular modifications and explanation of their benefits.

1. A cold air intake is sealed away from the hot engine air, and is located where it can take in more air.  Cold air intakes are equipped with a filter that can take in up to 300% more air.  Cold air takes up less space, so there can be even more air, all that air helps to burn all the fuel providing more power and better fuel economy.

2. Diesel chips make alterations to how the fuel is delivered to the engine, making it more efficient and more powerful.

3. A bigger exhaust or a mandrel bent exhaust (keeps the tube round, and the size constant) improves exhaust flow. Getting exhaust away from the engine is just as important in combustion as getting air into the engine. There are exhausts now that will even vacuum exhaust away from the engine, making it so that the engine doesn’t have to do that work.

All of these modifications add to the fuel economy of the diesel engine, over time they will actually pay for themselves in gas savings, and will continue to keep your money in your pocket for years after they are paid for. Diesels are the wave of the future and more and more economy vehicles are being produced in diesel versions because they are capable of so much better economy. – Nathan Young

S&B Filter – How To Clean Your Diesel Performance Intake

February 6, 2008

Diesel performance intakes are an incredible way to increase horsepower and lower exhaust temperatures.  There are two main concerns that people have with using cotton gauze filters.  First is that they think the oil might mess up the Mass Airflow Sensor. Secondly, that once the oiled filters get dirty, they let dirt in that will affect the turbo and engine in the long run.

As long as you keep your filter clean, and clean it with the precision oiling kit from S&B Filters, you wont have to worry about messing up your Mass Airflow Sensor because it will have the perfect amount of oil on it.  Shop Parley’s Diesel Performance for all your performance diesel part needs.

Darwins Theory of Diesel Performance

December 24, 2007
If Darwin himself were alive today, I dare say that he would be driving a diesel. No other engine out there has more perfectly illustrated his theories of evolution than the diesel.  Now as true as it might be that diesels were once known for being the “slow and smelly” vehicles on the road, car makers as well as several aftermarket performance companies have set out on a mission to put an end to that reputation.  With the additions of a turbo or multiple turbos (i.e. ’08 Powerstroke) and intercooler(s) as well as diesel performance intakes, diesel performance chips/modules and exhaust systems the reputation once held by diesels is now evolving, Darwin would be so proud.So why diesel performance? In the past there never really was a question as to which “species” was more dominant when it came to performance. It has not been until recently that there has even needed to be a debate as to which is better, gas performance or diesel performance and even today you will have people try to argue that gas performance is where it is at but I am here to say that not only is there more horsepower available for the money when it comes to performance products for diesels but you will have longer engine life as well as maintain if not increased fuel mileage.One of the strongest points in the argument for Diesel Performance is the fact that you can add engine mods to a diesel engine and it won’t harm the engine or make it burn hotter to the extent of damaging the engine permanently. Don’t get me wrong you can still fry your engine but diesel engines are built much stronger and much more durable. One of the main reasons that diesel engines are so durable or will last longer in general is the way that combustion occurs in the engine. Diesel engines “fire” or “combust” differently than gas engines mainly because of the type of fuel that is used. In gasoline engines a spark plug is used to combust the fuel but in a diesel combustion occurs mainly due to the temperature of the compressed air which causes the fuel to ignite. Because of this diesel engines are built more durable because they have a higher compression ratios (20:1 for a typical diesel vs. 8:1 for a typical gasoline engine) it is being built to withstand this higher compression that makes these engines more ready for performance modifications straight from the factory.

As the diesel engine has evolved over the years turbo chargers have been added to increase power as well as increase diesel fuel mileage, this has made way for huge increases in horsepower both stock as well as with the addition of after market products. One of the main reasons that diesel performance is so much more viable is the fact that because the engine is built for a higher compression ratio anyway so it is going to be able to withstand the boost that is created by a turbo much better than a gasoline engine, also allowing the addition of performance modifications without shortening the life of the engine as usually happens with gasoline engines when performance mods are added.

Like it or not diesel performance is here to stay, and whether or not you believe in evolution it’s happening and will continue to happen in the diesel performance market. Don’t be surprised when you see good old Darwin himself roll past you on the street in his tweaked out diesel.

Diesel performance evolution starts with a strong base of upgrades, not just any diesel performance part will do. – Nathan Young
