The APR Boost Tap provides a clean, reliable reference point for a boost gauge or other pressure accessory. The complete kit includes a billet boost tap, a stainless steel barbed connection point, two Viton O-ring seals and a tapping tool, plus a T-fitting for adding a second reference source and a brass no-buzz restrictor pill that cures gauge flutter on mechanical gauges. Roughly 96 inches of 200 psi hose is supplied with OEM-style ear clamps, black cable ties and anti-seize for neat routing through the engine bay.
