Product Description
K&N Engineering 57 Series Gen II Air Intake Kits (FIPK's) by K & N air filters are built for many different vehicles and represent a dramatic improvement over a K&N O/E replacement filter alone; More horse power, fuel economy and engine torque for your car, pickup, sport utility vehicle or mini van. The 57 Series Intakes 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. We start with the largest conical shaped high-flow air filter we 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.

 Tahoe June 16, 2008
Michael P. Paulsen (South Redondo)
i installed this unit on my 2004 Tahoe. It was a little harder to install than anticipated. Took 3-4 beers. Had to cut a good chunk out of my fan shroud. Looks sweet though and definitely gave me some good power.
 Great throttle response, not better MPG August 24, 2007

I have put a K&N Fuel Injection Performance Kit Gen2 Air Intake Kit on my Chevy Tahoe and Honda Civic. One thing that is immediately noticable is the greatly improved throttle response. When you press on the pedal, it jumps off. We have not really enjoyed a significant improvement in MPG. It may help a tad, but driving style and tire pressure I think our bigger influences on the MPG you get.
When excelerating heavy, you will have a significant increase in engine noise. We actually like it, but some may be annoyed. The best part is not having the guys who change your oil trying to sell you a $10 air filter for $30.
