Audi A4 Boost Tap - APR - APR Full Kit - 2017–2022. This kit provides a dedicated, reliable boost and vacuum reference for your B9 A4, enabling clean installs of gauges, controllers, or data logging.

APR engineered this solution to avoid spacing the factory T-MAP sensor, helping prevent inconsistent intake air temperature readings. Using the included punch tool on a warm engine, a port on the factory intake manifold is carefully opened; the billet aluminum boost tap installs with dual Viton O-ring seals for leak-free operation. A stainless barbed connection routes to 96 inches of 200 PSI hose, secured with five OEM-style ear clamps and five black cable ties. A T-fitting supports multiple reference points, and the brass restrictor pill calms mechanical gauge buzz. Anti-seize and a tap cap are included.
