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.

 I think this product is great. If anyone out there owns a Ford Ranger with 4.0 liter buy this product. This motor must be drowning for air intake. I use to get 15 mpg now getting 17mpg. I know your'e thinking oh 2mpg . Did the math, pays for itself in 8 tanks, for me that's 2 months. Then I get the extra 8 dollars every tank. 400 bucks annually, its sick how much gas cost. Don't know how much hp I gained but had to be some and I dont ever have to buy another filter, thank you K  N . Some customer said his friend bought one for his Ranger after we got done Bitchn about gas and my mpg, thought why not, I've tried everything else. Pass it on Ranger fans.
