K&N's 57 Series Gen II Air Intake Kits (FIPK's) are built for many different vehicles and represent a dramatic improvement over a K&N O/E replacement filter alone; they use only non-metallic rotationally molded tubes that can reduce air temperature and decrease intake sound over a metal tube. Restriction can exist BETWEEN an air filter and the engine reducing the benefit of a K&N Air Filter. The weakest link in the airflow “chain” robs a vehicle of its natural horsepower. Often that weak point is the factory air path leading to the Engine. K&N Air Intake Kits virtually eliminate air path restriction by replacing the air filter and the entire air path to the engine. The aerodynamically engineered tube drives a massive amount of air into an engine, which translates into POWER.

K&N 57 Series kits are truly state-of-the-art. K&N start with the largest conical shaped high-flow air filter they can fit into the engine compartment while using factory holes and mounting points. This extra filter size provides even more airflow at lower restriction than a standard K&N O/E replacement filter that is limited to the size of the factory air box. The oversized air filter also captures and holds more dirt increasing the service life before a cleaning is required (up to 100,000 miles). When possible, the filter is isolated from high engine temperature by a heat shield designed to lower the temperature of the air entering the engine, which increases horsepower. Next we attach the filter to a rotationally molded tube made from interlaced High Density Polyethylene (HDPE). This process allows us to precisely shape the tube to reduce turbulence and accelerate airflow into the engine. This is why some of K&N's tubes have unique shapes that are specifically engineered for each application. Finally the tube is connected to the engine with adapters made from high strength materials such as silicon and reinforced nylon and ensures long life. Put all this together and you have the best high-flow intake system available today.

So far works great! took a while to install, and had a performance sounding annoying whine to it, but I got used to it quickly and now i love it.

Extremely happy with the K&N. Engine sounds deeper and more powerful, and it feels more powerful too. You can feel the difference. 1st test drive was awesome. Brought a smile to my face. Installation was simple. Will recommend to anyone. Ordered it on Friday and it came Tuesday. Worth every penny. Thanks to PFYC for the excellent service.

After installing this kit on my 06'Grand Prix GT I had to grin on the first test drive. What a huge change in my cars attitude on WOT and the new sound that brought on the grin to my face. The 50 mile round trip commute to work each day has become much more enjoyable with the new found power curve. Make this one of your first upgrades, I bet you will grin too.
