The K&N 57-9018 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Lexus IS300 models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your IS300’s 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 57-9018 air intake comes with a carbon fiber topped K&N high-flow air filter and a heat shield that installs into the previous air box space. Air is directed through an aerodynamically engineered intake tube into the engine’s throttle body for a guaranteed power gain. The air intake assembly accommodates the factory mass air sensor, fresh air intake, and a replacement silicone evap vent line. The oversized 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 the existing factory mounting points. The tools needed are a couple of screwdrivers, a socket set and several wrenches. K&N 57 Series FIPK's are street legal in all 50 US states and come with K&N's Million Mile Limited Warranty.

I have a 2002 IS300 Lexus. I installed the Typhoon 69-8700 kit several months ago. Prior to installing the kit my gas mileage on trips was maximum of 23.8. I just made a 1679 mile trip where my average was 25.3 for the entire trip, the highest was 27.08 and lowest of 22.94, speeds of 60 to 80 MPH.

I have used this air filter on my 1995 Lexus SC400 without any ill effects (this is in response to the other review). I use K&N filters on all three of my vehicles and have noticed some fuel economy improvement. I have never done any performance testing. K&N air filters will pay for themselves in the long run and keep throwaway air filters out of our landfills. These are good products and I have used K&N filters for over a decade.

Replaced the stock filter with this product in the Lexus. Better throttle response along with improved gas milage.
