S&B Cummins Diesel Intake Manifold Elbow Upgrades & Improvements

November 28, 2012

S&B Filters builds cold air intake kits and intake manifold elbows for many of today’s most popular diesel and gas powered trucks and SUV’s.  For years they’ve sold an intake manifold elbow for 1998.5 to 2007 Dodge Ram diesel trucks with the 5.9L Cummins engine.   Their cast aluminum elbows provided large gains in airflow over the stock Cummins manifolds.

With many thousands of these elbows sold and installed, S&B still wanted to make their product better, and they finally figured out a way to do it.   They went back to the drawing board to come up with an even better improved elbow, and the result is impressive.   Rather than cast aluminum, their new version is fully CNC machine cut and TIG welded.  Check out this beauty!

New S&B 5.9L Cummins Diesel Intake Manifold Elbow

S&B used advanced flow software technology to eliminate dead areas, streamline airflow and pinpoint optimal velocity.  This new and improved model comes with features that diesel enthusiasts were asking for, like an almost ridiculous 8 ports.  Now you can run water-methanol injection, nitrous, temperature sensors, whatever floats your boat.   All eight ports come with an airtight plug.

Most aftermarket elbows attach to the intake by running two bolts through the interior of the elbow. This restricts airflow and hinders performance. S&B Filter’s new elbow attaches with four bolts on the outside of the elbow.  This results in a tighter seal, increased airflow and better performance.

S&B Filters is a company that prides itself on testing it’s products both in-house and independently.   They have their products tested to ISO 5011 standards.  On this elbow, they had it burst tested, and the results were impressive.  For the test, both ends of the elbow were sealed, and water was pumped into the elbow until the point of failure.  The result?  The S&B elbow withstood pressure of 300 psi before it cracked at the weld point.  Even competitively raced diesels pushing 1000 horsepower would rarely see over 100 psi – mission accomplished.

If you’re interested in adding these types of premium performance diesel parts to your Dodge Ram, you’ll want to pick the correct manifold elbow for your truck.  If you have a 2003-2007 common rail 5.9L Cummins engine, the correct part number for your truck is 76-1004.  If you have a 1998.5-2002 24V Dodge diesel, you’ll need part 76-1007.  For all your Dodge Ram Cummins diesel performance needs, trust the pros at Parleys Diesel Performance.
