"Easy Installation. This intake really improves flow and you can feel the a more touchy accelerator. At, wide open throttle, its sounds like a beast under the hood. Also makes a great little hissing sound when it surges for air. Very satisfied customer here. -John from Los Angeles" —Jonathan J from Covina, CA bought a K&N 57 Series FIPK Air Intake (Fuel Injection Performance Kit) for a 1999 Lexus GS 400, GS400, 4.0L V8.
