GFB has built a reputation on solving the small plumbing headaches that come with turbo and wastegate installs, and this fitting kit is a good example of that practical approach. It's a straightforward adaptor set designed to connect a 1/8" BSPT external wastegate port to a standard AN-4 boost reference line, built from stainless steel for long term reliability under engine bay heat and vibration.

This listing covers a universal application, suitable for any external wastegate or boost control setup using a 1/8" BSPT port that needs to be adapted to AN-4 fittings. It's commonly used on aftermarket turbo kits, standalone wastegates, and custom boost control plumbing where a clean, leak free connection is required.
