The GFB VAG Mk5/Mk6 Boost Gauge Tap provides a clean and straightforward manifold pressure reference for 2.0 TSI and FSI engines, without the need to cut or permanently modify factory hoses.

Installation is tool-free, fully reversible, and takes around 10 seconds. The tap is supplied as a single clip-on component, ready to fit straight out of the packaging.

A ¼” forward-facing hose barb is used to improve hose routing and help prevent oil from collecting in the bottom of the vacuum line.

Sealing is handled by two Viton O-rings, selected for their resistance to oil and heat. The body is CNC machined from 6262-T6 billet aluminium and fitted with a brass hose barb for durability and secure hose retention.

Finished in black anodising and laser engraved with the GFB logo, the boost gauge tap blends neatly into the engine bay with an OEM-style appearance.

Removal is quick and simple, leaving no trace that the adaptor was ever installed.

Manufactured in Australia, this component is CNC machined and produced under a QMS ISO9001 quality system.
