Unlock more power and a meaner engine sound from your 2018+ Subaru WRX or STI (with the 2.5L turbo H4 engine) with this AEM Cold Air Intake.

It replaces the restrictive factory airbox with a high-flow aluminum tube and a large, washable air filter.

The included heat shield with a lid helps keep hot engine air out, so your engine breathes cooler, denser air – which can lead to noticeable gains in horsepower and throttle response.

The filter is oil-free and can go up to 100,000 miles before needing a cleaning (under normal conditions).

A popular and relatively simple bolt-on performance mod that delivers results and a great turbo whoosh sound.
