GMC Sierra/Chevrolet Silverado 2500HD & 3500 with Air Intake Increases Duramax Diesel Torque

AIRAID 202-129 cold air dam performance intake for the 6.6L Duramax engine

The AIRAID 202-129 cold air dam performance intake is designed to reduce airflow restrictions and increase torque in the 6.6L Duramax.

Put simply, torque is the wheel-turning power that gets your truck moving, and horsepower is what keeps it moving. Turbodiesel engines like the 6.6L Duramax are able to provide gobs of torque because a giant turbo is amplifying the already ample torque that's being produced during the diesel combustion cycle. Increasing the amount of cold air going into the turbo helps the engine to create even more torque, which will reduce engine strain and allow you to haul and tow with ease. Diesel cold air intake systems, like the AIRAID 202-129 cold air dam performance intake system, reduce airflow restrictions and increase your torque to the DuraMax. Plus, it will save you a bunch of money in the process.

Filter wrap for AIRAID 202-129 cold air dam performance intake for the 6.6L Duramax engine

For dusty conditions, AIRAID recommends the use of a filter wrap, like the 799-469, which is designed for the 202-129 kit.

The stock air intake system on the 2001-2004 Chevrolet Silverado HD 2500/3500 & GMC Sierra HD 2500/3500 uses a narrow intake tube with lots if tight bends and an air box that's only able to feed a limited amount of air into the thick paper air filter. The AIRAID 202-129 intake on the other hand, collects a higher volume of cold air by using an oversized SynthaMax air filter, surrounded by a self-sealing heat shield. That power-rich oxygen gets sent down a wide diameter AIRAID intake tube that's been roto-molded to reduce restrictions, so the air arrives at the cylinders in a steady stream, instead of in turbulent bursts. This allows your 6.6L Duramax LB7 to produce more torque throughout the rpm-band. It also enables it to make the torque at lower rpm's.

Along with making power, the AIRAID 202-129 saves you money because the AIRAID SynthaMax performance air filter is reusable. It uses two layers of specially blended synthetic material, to trap dirt and keep it there until you clean it.Larger dirt particles get ensnared in the top layer, while smaller contaminants get trapped in the second layer. Because the dirt is stored inside the filter, air can continue to flow through even when it is dirty. Then when it's time to clean the filter, you simply un-clamp it from the intake system, and clean it using the 790-558 AIRAID cleaning solution. This means you no longer have to buy those expensive OE air filters, and you even get a No-Hassle Lifetime Warranty.
