The K&N 57-1514-1 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 57-1514-1 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 air temperature sensor and crank case vent hose. The oversized conical 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 and requires commonly available tools. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.
Best purchase I have made for my jeep. It instantly made my jeep drive and handle much better.
By Bill from Charlotte, NC
Check your parts before installing! The kit for my Jeep came with a filter element for a Ford! Other than this minor issue, I'm very happy with the system. Definitely improved the performance of my TJ Wrangler. Quick and easy to install.

What a different Jeep! Goes crazy when I step on it! With Flowmaster exhaust! So fun!

Was easy to install

My Jeep is now a racecar
The con is my own fault...with the increased power and torque notice after the upgrade. I'm always taking off from stops with a heavy foot, now gas mileage was poor to start with but now it's gone to hell....lol
By M from Dallas TX
I should have bought this sooner
Well thought out kit with all the hardware you will need. Improved throttle response, already had a free flowing muffler, but now the engine wants to rev. Under normal driving improved fuel mileage by 1.5 mpg. Should have upgraded the day I bought the Rubicon.

Very simple to install. Looks great under the hood and I'm already seeing fuel mileage gains and better "pick-up"

I couldn't be more happy with this kit. You really notice the power gains around 2000rpm and that's when you can really hear the engine roar. The under hood look is fantastic and everyone loves it. I went with the K&N kit because I know the quality that they put into their product and have always been pleased. I believe the performance of most of the cold air intake kits is relatively the same but I am always impressed by K&N's dyno charts on each of their products. Keep in mind that K&N stands behind their oil-soaked filters and personally this has always been a plus in my book
Is a throttle body spacer provided with this intake kit?

Hello Alaska Jeep Guy
The K/N57-1514-1 does not come withy a throttle body spacer and is not compatible
with the spacer, I recommend an AEM21-8311DP Intake System. It make 13.3 more HP
and comes with the throttle body spacer and is designed to give the best performance
with the intake and throttle body spacer matched to work together.
Thank You for your question. Jon Snyder 4Wheelparts
Does the jeep (TJ Sport 4.0 L) get a deeper or throaty sound with this intake system? I have a magnaflow moffler and I want the jeep to sound deeper...so will this kit improve the sound?
And do does it get more mpg? Thanks

Hello Ivan, the K&N Filter 57 Series International Intake Kit part# K/N57-1514-1 will definitely give you a deeper throaty sound under acceleration. If you Drive moderately you will also see a mileage increase. Thank you for your inquiry.
