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.

K&N 57-9018 Air Intake Product Reviews

Review part 57-9018
Monday, November 30, 2015 - Part 57-9018
Was NOT easy to install. Took me 2 or 2.5 hours with a complete set of tools. Once installed, the intake was flawless. Loved the added sound- unnoticeable below 3000rpm, but pretty loud above that. The intake is not supplied with a cleaning kit. Instead of buying a cleaning kit, I just rotated the filter occasionally so that air from the grill hit a clean side of the filter. Loved it

Love it, super easy install. Instant gradification when accelerating, the growl and little extra pull.
