2008 Ford F-350 diesel

K&N has developed an air intake system (57-2576) for the 2008, 2009 and 2010 Ford F-250 Super Duty with a 6.4 liter V8 Diesel engine, the 2008 to 2010 Ford F-350 Super Duty with a 6.4 liter V8 Diesel engine, the 2008 to 2010 Ford F-450 Super Duty with a 6.4 liter V8 Diesel engine, and the 2008 to 2010 Ford F-550 Super Duty with a 6.4 liter V8 Diesel engine.

K&N dynamometer testing shows a 16.4 horsepower gain at 2600 rpm and a 25.73 lbft gain of torque @ 2500 rpm. This is more than an 8 percent increase in torque compared to the original intake for improved towing and passing power.

The K&N air intake tube was designed and shaped to provide the maximum amount of horsepower while staying within the factory parameters for this twin turbo application.  There is no need to re-program when you run our K&N air intake system.  The 57-2576 makes use of the factory mass air sensor and electric filter minder.

The lifetime replacement K&N air filter (RU-5172) is washable and reusable. It is made of six layers of cotton gauze for maximum surface area and filtration. With proper care diesel motors typically last longer than gas motors. Our K&N air filter ensures you will get the protection your diesel motor needs. Our air intake system includes a powder coated heat shield which isolates the K&N air filter from engine heat.

Designed to be installed in 90 minutes or less, our K&N air intake systems are backed by the famous K&N Million Mile Limited Warranty. Take a look at our 57-2576 installation video to see all the steps involved.
