The K&N 57-6014 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 57-6014 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 mass air sensor and crank case vent hose. 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 couple of screwdrivers, pliers, a socket set 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 57-6014 Air Intake Product Reviews

Tuesday, May 22, 2018 - Part 57-6014
I'll begin with the positives. I was very impressed with the added horse power. There was definitely a noticeable increase. I'm still checking the gas mileage, but it appears to be increasing. The kit was easy to install for an average car enthusiast like myself and took me approximately 2 hours to R & R. The kit fit perfectly with no adjustments necessary. Now the negatives. When I removed the kit from the box, I wasn't that impressed with the quality given the price paid ($329.99). Thus the 4 star rating. The intake tube looked cheap and the air intake sensor mount was not align properly, so I had to adjust the mounting screws to get it air tight. Also, I wondered why K&N didn't provide a heat shield with the rubber seal pre-installed. Fitting and trimming the rubber around the shield took me 15-20 minutes. I also needed to re-use one of my old hose clamps because one of the clamps provided did not fit over the throttle body. All in all though, the system is a great addition to my truck and I'm happy with the results. I would definitely recommend this kit.
