The K&N 57-2546-1 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 57-2546-1 air intake comes with a 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 tubes into the engine’s throttle body for a guaranteed power gain. The tubes accommodates the factory mass air sensor and air temperature sensor. The oversized oval 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 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.

Easy step by step installation, amazing timing on the shipping. I have a ford 350 with a 6.0 and any one that has one knows the 7.3s are way better but after I put this on it was an amazing difference in truck all together, worth the money.

Directions were actually put together, install was easy. I get slightly better fuel mileage and throttle response. If you are considering this product just go ahead and get it, once it is installed you can tell the engine can breath better.

Easy install on an 06 F250, with 90k miles, saw a increase of 4mpg and quicker throttle response. Good product.

I was quite surprised on the quick delivery, till I found out you were in Riverside, Ca. Everything was neatly packed and the instructions were easy to follow, even tho it took my son in-law and I 8 hours to remove the old intake and filter and install the new K&N intake and filter. Performance seems to be better, as my truck has 4.88 gear ratio and is set up for towing. I will be hoping for the 2 miles per gal. increase, as next month, we'll be going up to Northern Nevada, for some Deer and Elk hunting and I'll be towing a 40' travel trailer.
