Air Filters for Duramax Diesel – Buyer’s Guide!

The Duramax diesel engine is a GM V8 engine that is fabricated by DMAX as part of a joint venture between GM and Isuzu. The first Duramax 6.6L engine reached the market during 2001 in Chevrolet and GMC trucks, pickups, medium duty truck, and vans. There are over 8 different Duramax categories providing different levels of performance.

The categories include LB7, LLY, LBZ, LMM, LGH, LML, LMK and L5P

Each engine category is different from the other, and some models come with multiple variants for different applications:

The latest model is the Duramax LP5. This category was released in 2017, and is the most powerful of the series with 445 hp @ 2,800 rpm and 910 lb-ft @ 1,600 rpm. With some basic upgrades to the design specifications, performance can exceed 550 bhp @ 3050 rpm and 1050 lb-ft at 1975 rpm. As such, aftermarket upgrades will turn this model into a beast.

Cold Air Intake Filter Kits

A cold air intake filter kit is guaranteed to improve any engines horsepower and torque performance. Aftermarket kits are designed to provide better airflow rates, cleaner air and in some instances boosted air that helps support turbocharger systems.

Most models are very easy to install, and a good kit will only require basic tools such as a screwdriver, plier and ratchet set. The time to replace is around 90 minutes. The best replacement kits come with OEM style holes and connection shapes and sizes so that you don’t need to drill or adapt any part during the installation process. Kits are vehicle specific, so you do need to ascertain your exact model before buying and pairing a kit.

The large filter maximizes high-flow filtration that helps the engine to run cooler and accommodates engine movement. This model prevents component damage and outflows stock and competitors with a 35% improvement.

This improvement is reached through reduced exhaust gas temps (EGTs), and exclusive 5-inch bellows that prevents component damage and the oiled air filter.
