If you are purchasing this cold air intake with hope of increasing fuel economy, keep reading, and click on the red letters, they're helpful. Just installing a cold air intake isn't going to do much for your fuel economy. It's a vital peace to a valuable package. Increasing air flow into the engine is going to help with fuel economy and performance. As we pull more air into the engine, we have to let more air out.
If you are wanting the absolute best performance we highly recommend a free flowing aftermarket exhaust to replace the VERY restrictive factory equipped exhaust. Installing an aftermarket exhaust and cold air intake requires custom tuning to make sure you get the absolute best in performance from your new upgrades.
The last peace of the puzzle is your fuel system, the Duramax Diesel engine is the only diesel used in a light duty pickup truck, that doesn't have a lift or supply pump. That's where we highly recommend a Fass Fuel system to complete this package.
With the intake, exhaust, custom tunes and the fass installed, we have seen some very impressive fuel economy gains for our customers.
