GFB VAG MK5/6 Boost Gauge Tap for VW Golf GTI – Clean Manifold Pressure Port for Accurate Boost Monitoring

Discover the GFB VAG MK5/6 Boost Gauge Tap (Part #5800), the direct solution for adding a reliable manifold pressure reference port to your 2.0 TSI/FSI engine. This boost gauge tap installs in seconds without tools, delivering precise boost readings that keep your turbo setup responsive and your drive data trustworthy. Unlike makeshift adapters that clutter the engine bay or risk leaks, this tap clips directly into the existing manifold port, ensuring a secure fit that withstands daily commutes and track days alike.

Engineers at Go Fast Bits designed this tap to eliminate common issues with aftermarket boost monitoring. The forward-facing 1/4" hose barb simplifies routing and prevents oil from collecting in the line, which means cleaner signals to your gauge and fewer maintenance headaches. Built from billet 6061-T6 aluminum with a brass barb and oil-resistant Viton O-rings, it resists corrosion and holds up under high-pressure conditions. The black anodized finish and laser-engraved GFB logo blend seamlessly into your VW's engine bay for a factory-fresh look.
