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

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.

Choosing the Right Diesel Performance Exhaust System for Your Diesel Truck (part 1 of 2)

It’s widely known that upgrading your factory system to a performance diesel exhaust is a great way to increase your engine’s power and fuel economy.   Because of all the changes to stock emissions systems over the past few years, there now exists some confusion and questions among diesel owners as to which exhaust upgrade is the best option for them.   Parleys Diesel Performance wants to help you make an informed and educated choice, so let’s start by reviewing the basics.

Traditionally, light duty diesel truck factory exhaust systems were 3 inches or 3.5 inches in diameter, with crimped spots along the diesel exhaust system that hampered flow and robbed your vehicle of its true potential.   Installing a performance system to increase the diameter of your exhaust allowed your engine to expel exhaust gasses more efficiently, and mandrel bends gave your exhaust a true 4″ diameter.  Diesel trucks today come from the factory with catalytic converters, diesel particulate filters, even urea injection systems (also called SCR or selective catalytic reduction).  And 4 inch stock exhausts are commonplace.

So which exhaust should you choose for your truck?

If you have a “pre-DPF” diesel pickup (anything before the 2007.5 6.7L Cummins, 2008 6.4L Powerstroke, or 2007.5 Duramax LMM) the most common diesel exhaust upgrade is a four inch turbo back exhaust system.  The standard 4″ diameter will meet most people’s needs; however, if it’s your intention to upgrade your vehicle to a high horsepower level (think over 550HP), we recommend you invest in a 5″ diesel performance exhaust system. This will allow the larger amount of exhaust your high horsepower diesel creates to flow properly and keeping temperatures down.

In addition to figuring out the diameter of the exhaust system you want for your truck, there are also some other important choices to make.  Diesel exhaust systems come in four main materials: T-304 Stainless Steel (high-polish show finish quality), 409 Stainless Steel , Aluminized Steel (similar to your original stock exhaust), and different variations of Black Stainless or Black Aluminized Steel.   You also need to decide whether you want to have a muffler or not, and if you do choose a muffler, do you want one that is a high flow performance muffler or one that keeps your exhaust volume low.  The majority of Turbo-Back Exhausts come with high flow performance mufflers.  If you want a “straight pipe” exhaust, meaning no muffler, a popular choice is the no-muffler series from MBRP Performance Exhaust.  Their stainless steel SLM (Stainless Less Muffler) and PLM (Performance Less Muffler – this is aluminized steel)  are very competitively priced and work great.

Although less popular, catalytic converter or Cat-Back Diesel Exhausts allow you to upgrade the sound and flow of your exhaust and in some areas are necessary to keep your diesel street legal.
