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.

 This system was well designed and made for a clean looking installation. I bought it to improve mileage. I took a 1300 mile trip in this truck last week. The performance improvement was noticeable and the MPG was improved by about one MPG. The truck growls a little more but that's OK. Good product.

 This is the third kit I have put in three different vehicles. I also use K&N filters in my jet skis and my quad. I'm sold on the performance and have been using K&N products for more than 15 years. This kit I put on to my Nissan Titan has good horsepower, but I know this will add to it and more importantly when driving on the highway I get better gas mileage. I use K&N for filters on all my vehilces and also use their oil filters. Great product, easy to install and will last for longer than you own your car. I would highly recommend buying this product and installing it on your car or truck.

 The kit was easy to install and now my truck really growls!
