57-2559) that will add power to the 2005 Ford Focus 2.3L and 2005 Ford Focus 2.0L excluding the PZEV models.
Dyno-testing revealed that this K&N FIPK (57-2559) added 11.85 horsepower at 5797 RPM. By replacing the restrictive factory airbox your engine will get more air with less restriction. More air means more usable power and acceleration throughout the engines RPM range. "We put the FIPK toward the front of the car," said K&N Performance Kit Manger Bert Heck. "We had to mold the tube and tune it to the vehicle for the power gain."
K&N began with one of its famous Extreme Top High-Flow Air Filters (RX-4990). The Air Filter can be washed and re-oiled with a K&N cleaning kit.
The K&N filter attaches to an aerodynamically designed intake tube that's made of polyethylene. "The tube was designed to keep the cool air on the intake side," said Heck. "The power gain is really good considering the size of the motor."
Installation is easily completed for the FIPK (57-2559) in 90 minutes or less with simple hand tools. No drilling is required, and the 57-Series air intake includes illustrated instructions as well as all the necessary mounting hardware. It also comes with K&N's famous Million Mile Limited Warranty.
