The 57 Series Generation II air intake, also referred to as an FIPK, is K&N’s ultimate performance product. These performance intakes are designed to increase power by as much as 10%. 57 Series FIPK’s are CARB exempt, meaning they are street legal in all 50 US states. They come with a Million Mile Limited Warranty and are guaranteed to increase power. K&N air intake systems replace your vehicle’s restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This translates into more power and torque for your vehicle. The filters on these kits are washable and reusable.
K&N engineers tested the 2005 Chevy GMC 2500HD with the 6.6L LLY Duramax on their in-house dynamometer and results showed a 20 horsepower increase with this intake system. See the Dyno Results
The 57-Series Intake Kit consists of a high-flow K&N Air Filter that can go up to 100,000 miles between cleanings depending on driving conditions. Cool clean air travels through K&N’s specially designed intake tube to the engine for more power. The washable, reusable high flow K&N Air Filter is designed to increase horsepower and acceleration while providing excellent filtration.
Covered by the famous K&N Million Mile Limited Warranty, the 57- Series Intake Kit is easy to install using simple hand tools in 90 minutes or less. This will be the last air filter your truck will ever need.
