K&N Fuel Injection Performance Kits (FIPK®) contain a high flow K&N air filter with uniquely designed adapters. This creates a radius entry allowing the engine to ingest air with less restriction compared to the factory intake system. FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty. K&N air intake systems replace 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. More air means more usable power and acceleration for your car or truck. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available (see installation instructions). [MORE]

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.
Bill, Michigan
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
