Product Description
The kit replaces your vehicle's restrictive factory air filter and air intake housing. K&N intake systems are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger volume of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable, reusable and easy to install with tools commonly available.

Installation instructions were a little vague and the heatshield bracket is a little "flimsy." Other than this the product is excellent. I noticed an immediately increase in throttle response and fuel mileage.

30 Minute install. Package arrived complete. Completely fits my car. No irreversible mods to my car. A straight swap to the original air filter kit.Cannot feel the actual increase in HP as expected but the sound is great!Installed in a Honda Civic Si (99) and on idle the sound is the same as stock, same with gradual push on the gas pedal even if you rev till red line (as long as its gradual increase the sound will be like stock), but when you floor it, then you hear the loud sound, especially when Vtec kicks in until almost redline. :)Thing to note, upon shut down of engine you will hear the filter sucking air for up to at least a few seconds after, which forums say is normal.
