The BLOX Racing dual‑pattern inlet flange accepts both T3 and T4 turbo inlet bolt patterns with an open port design. It provides a universal mating surface for aftermarket manifolds and turbocharger inlets where adaptability between T3 and T4 footprints is required. The flange allows fabricators and installers to mate different turbos without custom modification to the inlet face.
