The K&N 57-9011 FIPK air intake system replaces the restrictive factory air filter and air intake housing in some Lexus GS400 models. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your 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 57-9011 air intake comes with a chrome 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 tube accommodates the factory mass air sensor and vacuum line as well as two replacement silicone vacuum lines. The oversized cone shaped 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 existing factory mounting points. The tools needed are a screwdriver, a ratchet 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 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.

WOW...what a difference having replaced the stock Toyota air filters with K&N replacements. I used the plural because the Lexus LS460 has 2 separate air filters. The car is an absolute BEAST having easily raised the horsepower to over 400+ while maintaining similar fuel economy. I'll probably get better MPG when I stop stomping on it just to feel the POWER! Replace the stock chip and void the warranty...absolutely no way. But changing the air filters (and NOT VOIDING the warranty) seemed way too easy. I was so impressed I bought new filters for my wife's GS460 and our Toyota Tacoma 4.0 V6. Both have dramatic increases in power and fuel economy albeit, she's having problems with not stomping on it as well. Who ever came up with this idea for passenger vehicles kudos! Can you do the same thing for HVAC units? I want to feel the polar blast save energy and make my wife a human pop sickle! With GREAT admiration....
