The K&N 57 Series FIPK 57-3021-1 air intake system replaces your vehicle’s restrictive factory air filter and air intake housing. K&N air 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 57-3021-1 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. The placement allows air to be directed past the mass air sensor through an aerodynamically engineered 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 usually in 90 minutes or less using the existing factory mounting points and mass air sensor requiring only a screwdriver, ratchet 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 57-3021-1 Air Intake Product Reviews

Thursday, December 8, 2016 - Part 57-3021-1
This was awesome. From the ordering and quickly shipped process, to the clear installation instructions, it was easy. The booklet said 1.5 hours start to finish and it only took @ 70 minutes. What a difference it has made. K&N claims a modest gain of @ 9 hp (I think) but it feels more like 20. I also put on a dual Magnaflow cat-back system 2 days prior. I have a 2002 GMC EC 4x4 with a 5.3L v8. Wonderful and highly recommended. Hal

Great product, easy install. The only difficulty was that one lock nut and bolt were missing. I was able to get one from the hardware store though.

Horsepower gain is what I have come to expect from K&N's intakes. What I didn't expect was the almost 3 mpg' I received. Thanks K&N for the nice surprise.

Product works great but instructions a bit deficient. Clearer photos and more tips on putting parts together would help. (Eg. Use a twisting motion to connect tubing to fittings, otherwise the rubber might bunch up and/or buckle). But, as I say, product works great. I've now installed three such systems (my BMW took an (Brand Name)).
