The K&N AirCharger 63-6012 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 63-6012 air intake comes with a large chrome topped K&N high-flow air filter and a heat shield that mounts onto the inner fender. 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 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.

 I have had K&N air filters on all my vehicles over the years. This is the first Aircharger Kit. It was installed on a 2012 Nissan Titan 5.6L V-8 engine. The enclosed instructions were very precise and it took me a little under 2 hrs. to complete. This kit can be installed by a novice mechanic, and expect no surprises, as I had none. Performance after installation definately improved, very little acceleration required to cruise speed. Although it's too early to tell, I expect better gas mileage if it's anything like my other K&N filters.!

 Recieved product in mail the next day when I got home to pre-fab the intake so that when my wife came home I could install intake. It only took me about 20 mins. to install turned over the key and the engine sounded great. Went on a test run and preformance was excellent we started off at a little over 15 miles to the gallon. After intake was installed with a full tank of non-ethanol fuel our mileage went up to 17.49. It's a start better, than it was.
