The K&N AirCharger 63-1108 air intake system replaces 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 factory air filter assembly. More air means more usable power and acceleration throughout the engine’s RPM range. The 63-1108 air intake comes with a K&N high-flow air filter and a heat shield that installs into the previous air box space. This allows cooler, denser air to be directed through a custom molded intake tube into the engine’s throttle body for a guaranteed power gain. The oversized air filter can be used for up to 100,000 miles before servicing is needed depending on driving conditions. This air intake is relatively easy to install requiring only a couple of wrenches, a socket set and screwdriver. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Product Reviews      Review part 63-1108

 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.
