K&N 57-Series FIPK® Unleashes '04-05 GM Duramax Diesel Power

RIVERSIDE, CA - GM one-upped the light-duty diesel torque wars by introducing the LLY-series Duramax diesel for 2004-2005 Chevy and GMC 2500 and 3500 trucks. The engine's class-leading 605 lb-ft of torque provides serious towing power. Still, there was room for improvement. Enter K&N engineers. The leader in airflow technology, K&N unlocks more rear-wheel HP and extra torque with a new 57-Series Fuel Injection Performance Kit (FIPK®), Part No. 57-3047, for the LLY Duramax.

Clean air is critical for diesel engine longevity. K&N is able to significantly increase airflow to the engine while improving particulate-trapping capabilities compared to the stock paper filter. This happens through the famous K&N High-Flow Air Filter's aerodynamically engineered pleats. Construction consists of four layers of oil-impregnate cotton-gauze sandwiched between stainless steel screen to capture particles as small as 5 microns. The cotton filter medium traps dirt, and the pleats' pitch and depth accelerate airflow into the engine. Backed by the K&N Million Mile Limited Warranty®, this filter can be repeatedly washed and re-oiled with a K&N Recharger® Kit. Service intervals are now as high as 100,000 miles.

After exiting the filter, incoming air travels through a free-flowing polyethylene intake tube that's routed for the least restriction possible. The system's heatshield keeps incoming air as cool as possible.

The LLY Duramax 57-Series FIPK® is designed for do-it-yourself installation. The bolt-on kit comes complete with all necessary hardware. Existing holes are used, so no drilling is required.

K&N also offers a washable/reusable OE-replacement air filter for the LLY Duramax (PN 33-2135) as well as a premium-quality Performance Gold Oil Filter (PN HP-3003) - highly recommended for keeping oil clean to maximize diesel longevity.
