Injen 01-03 Lexus GS430/LS430/SC430 V8 4.3L Black IS Short Ram Cold Air Intake
This Injen IS Series short ram intake system installs in the factory airbox location on 2001-2003 Lexus GS430, LS430, and SC430 models with the 4.3L V8 engine. It replaces the restrictive stock setup with a smooth-flowing aluminum tube and high-flow filter for noticeable gains in horsepower up to 9 HP and torque up to 10 lb-ft at the wheels. Drivers experience sharper throttle response and stronger mid-range pull right after installation.
Key Features

- Stock Location Fitment: Bolts directly into factory mounting points without cutting or modifications for a clean underhood appearance.
