A sister product to our 57 Series FIPK, our 63 Series AirCharger® Air Intake Systems are guaranteed to increase horsepower. 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 allows your vehicle's engine to inhale a larger amount of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available (see installation instructions). These Air Intakes cannot be sold in California. They are not legal for use in California or other states adopting California emission standards.

K&N 63-2587 Air Intake Product Reviews

Monday, May 23, 2016 - Part 63-2587
Installed the K&N 63-2587 on my 2014 Ford Fiesta ST. Installation only took about a half hour & was simple following the step by step instructions. The K&N cold air intake provides better throttle response along with a cool sound. For those who are worried about heat soak, its only s couple degrees higher than the restrictive factory air box. The only way you would get heat soak is if you were stuck in traffic in 100 degree weather. I live in New Jersey where it can get 90 plus degrees with high humidity & I have never had an issue. I have no regrets putting this on my car. It was money well spent. You can feel the difference as soon as you drive it.
