The K&N 57-2505-1 FIPK air intake system replaces the restrictive factory air filter and air intake. 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 57-2505-1 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 and into the engine’s throttle body for a guaranteed power gain. The air intake system accommodates the factory mass air sensor and air temperature sensor. 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.

Part was a perfect fit. I've always put in K&N filters in all my cars, love them. Glad you had one for this old of a car, 1988 Ford Thunderbird Turbo Coupe.

A while back, I came across a K & N filter advertisement in an auto magazine, when I owned an old 1987 Ford Thunderbird.  It was running rough and acceleration was steadily declining.  After deciding to simply install a K & N drop-in filter, I was shocked and relieved to discover that the company's claims for added performance were actually true. The 5.0 liter engine's acceleration was dramatically enhanced, MPG improved, rough idle was eliminated, and shifting points became smooth.  Later, I dropped one into my 2003 Dodge Stratus Sedan R/T and immediately noticed dramatic improvements in throttle response and gas mileage (over 3 MPG).  I recently purchased a 2009 Pontiac G5 with the 2.2 liter Ecotec engine.  After immediately installing a drop-in K & N air filter, this light-weight vehicle has exceptional gas mileage, and performs like a V6.  After experiencing the quality of K & N, I'm tempted to upgrade my G5 with the K & N Typhoon Air Intake soon...

All I can really say is WOW. This air filter is fantastic. I own a 1996 v6 Ford Thunderbird and the pep my car achieved after installing the K&N factory replacment air filter, I will now never buy another air filter from any other company .

Thank you
