K&N 57-3501 Air Intake

57 Series FIPK > Performance Intake Kit
  • Guaranteed to increase horsepower
  • Designed to improve throttle response and engine sound
  • Easy to install, usually in 90 minutes or less
  • Washable and reusable lifetime air filter
  • Lasts up to 100,000 miles before service is required (depending on driving conditions)
  • Replaces entire factory air intake system
  • K&N Million Mile Limited Warranty
The K&N 57-3501 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Acura Integra models. 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 57-3501 air intake comes with a chrome topped K&N high-flow air filter that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body intake for a guaranteed power gain. 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 existing factory mounting points. The tools needed are simply a screwdriver and ratchet set. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

Customer Feedback

Dear K&N, I recently traveled across country from South Carolina to Utah. My old filter needed a change and my Dad told me how much difference in gas mileage he got with your air filter. He drives a Ford F150 and I have a 99 Buick LeSabre. I have to admit that the cost of the filter had deterred me for years in buying one. But not anymore, I did buy one at the local Advance Auto before I left to move out west. In general I used to average 21mpg around town and 26 to 27 on the Interstate. My Buick has 121k miles on it so I really wasn't expecting much. My car was loaded down as far as I could safely and legally go. I averaged 27mpg in the mountains and 30 to 31 on the straight and flat areas of the Interstate. Incredible gains considering how loaded down the car was. A/C was used about 75% of the time. Now that I am living in the big city with stop and go traffic, my MPG today at the pump was 25mpg. I am grateful that I got the filter. As you can see I have gained 3 to 4 more miles per gallon. I figured that the filter paid for itself just in the trip alone. And now that it's paid for I will never have to spend money on another filter but just the upkeep and maintenance on the one I have. Thank you very much for a wonderful product! I just can't believe I didn't buy one years ago.

Weather in Seattle can be unpredicable, one hour it's beautiful then the next its a heavy down pour. Having the filter wrap around my K&N filter sure did what it was suppose to do and its repelling water. I have a CAI on my Acura Integra. I would fully recommend purchasing this product along with your K&N air filter!! I am definitely buying one for my truck when I have the money!!

I have recently bought a RX-4990 air filter and it has made a huge difference on my 1992 Acura Integra GSR, with a cool air setup this thing runs smoother and has improved my gas milage. As in the pass I know K&N air filters will otulast and outperform others. K&N for life.
