OTL Billet Injector Housings - 2002-2007 Subaru WRX (Stock Manifold) / 2004-2021 STI

Fuel System Upgrade

If you’re looking to upgrade your fuel system to a top feed setup, these Off The Line Performance billet aluminum injector housings for your Subaru should be on your list! The double O-Ring design provides a strong seal for high boost levels while not needing to use gaskets like you’d find on other injector housings.

Increased Air Flow

The Off The Line Performance billet injector housings provide much better air flow from the manifold into the engine than the stock housings, meaning more horsepower! Comes in either RAW or a powder coated black finish. The sliding center mounting bolts also make fitting multiple different manifolds a breeze.
