The K&N AirCharger 63-1008 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 63-1008 air intake consists of a chrome topped K&N high-flow air filter that directs air 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 using commonly available tools. This air intake cannot be sold in California. It is not legal for use in California or other states adopting California emission standards.

Dearest K&N,
I recently purchased a K&N air filter for my 1996 Ford Mustang GT (4.6L) and I must say that acceleration and HP has increased significantly.
I'm no stranger to K&N air filters because my first car had one and my father's Tundra and my mother's Camaro both have them.
I love it when I give it just a little gas and the crisp throttle answers with easiness. I put the pedal at WOT (wide open throttle) and to complement the dual mufflers, the intake noise of all that air gushes through the engine and air box. I am very pleased with the product and I'll stand behind it 100%!

Outstanding products. Purchase two K&N filters, one for my 2008 Gmc Sierra and one for a 2008 Ford Mustang GT. Noticed an immediate increase in horsepower. Thank you.

I've replaced OEM air filters with the equivalent K&N filters in all my vehicles for the last 10 years or so. I've never really seen any appreciable increase in mileage using the replacement filter cartridges, but I can feel a gain in horsepower in the weak little 4 cylinder cars I've had. When I bought my 2008 Mustang GT I decided to splurge and get the CAI kit No.63-2565. Not only did I gain about 10 HP at the rear wheels, but my highway mileage jumped from 27 mpg to 31 mpg cruising at 70 mph. Not too shabby for a 300ish HP V8 engine. If K&N made a CAI kit for my Ford Ranger I'd buy it. It's not a race vehicle, but I'm sure I would enjoy a little more HP and better mileage, although 27 mpg highway isn't bad for a small P/U truck.
