The K&N 57-6005 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 57-6005 air intake comes with a K&N XStream Top air filter designed for higher air flow and durability. A heat shield installs into the previous air box space that directs air through an intake tube into the engine’s throttle body for a guaranteed power gain. The oversized air filter accommodates the factory air temperature sensor and 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.

K&N 57-6005 Air Intake Product Reviews

Thursday, June 23, 2016 - Part 57-6005
I want to personally thank you all at K&N. Your product is literally the reason my Xterra passed smog. This truck holds a lot of sentimental value to me and I struggled for a year and a half trying to get the thing registered. The old intake was aftermarket and didn't match carb numbers. So I figured I might as well go with a K&N because I knew it was carb exempt and would pass smog for sure. You delivered the product in record time and install was a breeze. Took it to get smogged the next day and it passed. Not only do I love the fact that it passed but it also really boosted the performance of the engine. Noticeable gain in low end torque and less lag in low rpm, it gets up to speed much better now and also sounds like a beast. I will be a returning customer and once again, thank you!

Awesome product. Easy to install and makes a easily noticeable difference. Thanks for the good products you make. One thing though, I have a throttle body spacer and the holes for the mounts don't line up but I just drilled the appropriate holes with ease and it holds very tight not worried at all with off-roading with this filter set up. Doesn't bounce around like the homemade one I did.
