ETS 04-07 Subaru STI Titanium Intake Kit

This titanium intake puts the filter in the fender well to feed the STI turbo away from engine-bay heat. I'd choose it when inlet flow, weight and the titanium appearance all matter to the build.

This listing is the speed-density version, so the ECU must be configured to use suitable pressure and air-temperature inputs instead of relying on the factory MAF. Choose brushed or burnt finish for appearance and arrange the correct calibration before installation.
