OTL Billet Quad Injector Housings

If you’re looking for a fuel system that can support unlimited power, these OTL billet aluminum QUAD injector housings 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. These also provide much better air flow from the manifold into the engine than the stock housings, meaning more horsepower! The sliding center mounting bolts also make fitting multiple different manifolds a breeze.
