The K&N 57-2511 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Ford Mustang 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 57-2511 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 the air filter, past the factory mass air sensor and into the engine’s throttle body 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 requiring commonly available tools to do the job. 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

I bought a K&N Filter for my 1995 Ford Mustang GT 5.0 302.
I was Running my car with a stock intake pushing custom pulleys chopped flow masters. MAN CAN I TELL THE DIFFERENCE!!!!!!!
But, I lost my K&N sticker, so I can't represent.

My K&N results

I own a 95 Mustang GT 5.0, I bought the FIPK (air intake) for it, WOW!!! What a difference, more power, better acceleration, slight mpg increase very pleased, so much so I bought the drop in filters for my 96 Chrysler Town and Country Minivan with the 3.8 v6, also my wife's 2002 Dodge Caravan with the 3.3 v6 both were amazing, better sounding, faster acceleration and better mpg, I also drive a 92 Ford Explorer XLT 4.0 v6 5 speed as an escort vehicle for modular homes. I honestly was getting 23 MPG with stock air filter driving over 1,000 miles a week. I bought the drop in filter to see if I could better my mileage, so I tested it for 1 month so far and I am SHOCKED. I am now getting 27.2 MPG in a Ford Explorer!!!!!!!! Anyone who owns an Explorer will tell you that 27 mpg is incredible, if not almost impossible, but it is true

Thank you so much for an amazing product that pays for itself, and has a 1 million mile warranty, finally a company that delivers on their claims..

I have tried "high performance" filters from other companies, you know the green ,blue, and the orange filters but they were nothing compared to the K&N.

A K&N customer for life!!

Simply the BEST on the market. I have used them in all of my vehicles. They are easy to install and you will immediately notice a boost in power and a small improvement in the gas mileage. Easy to clean and very durable. Spend the extra money and try one in your car or truck. You will save that money the first year in gasoline. I have them in my 2014 Mustang V6 Coupe and my 2013 Ford Explorer XLT V6.
