Your 2001-2005 Lexus IS300's 2JZ-GE engine deserves better than the factory airbox. This Flashark Cold Air Intake Kit replaces the restrictive stock setup with a single Φ70mm aluminum intake pipe and a high-flow red cone filter — giving your IS300 sharper throttle response, smoother power delivery across the rev range, and that aggressive induction tone the stock system completely kills.
Built specifically for the Base Sedan and Sportcross Wagon with the 3.0L DOHC inline-6, this kit bolts to factory mounting points using the integrated bracket. No drilling, no cutting, no fabrication. About 60 minutes with basic hand tools.

FAQ

Q: Does it fit the IS300 with manual transmission?

A: Expect 5-10 wheel horsepower on a stock 2JZ-GE. The biggest difference is throttle response and smoother power delivery across the mid-range.
