The K&N 57-6012 FIPK 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 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 57-6012 air intake comes with a chrome topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The tube accommodates the factory mass air sensor and crank case vent hoses. The oversized cone shaped 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 usually in 90 minutes or less using the existing factory mounting points. The tools needed are a screwdriver, a ratchet set, pliers and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

K&N 57-6012 Air Intake Product Reviews

I bought this air intake because I needed the smog sticker. Cost me roughly $300 to replace the old one, but I got my truck smogged. Works as advertised as far as I can tell and I would purchase another for future vehicles.

I love my K&N filter, it made my Nissan Titan a whole different truck. The gas mileage is better, performance is outstanding and very easy to install. I would recommend this to any one looking to get better performance out of there vehicle. The only thing I regret is not installing it sooner.

Received my order in a timely matter. Install instructions were easy to read and follow. Only problem I had was with the silicone hose being super slick, and didn't stay connected when tightening the hose clamps. I contacted the service department, explained my problem and they shipped one out next day. All is well now, thank you for your customer service. I will recommend K&N products to all of my friends. Thanks again, Bill
