Angry Ass | S38B38 Vacuum Supply | Variable Resonance + Secondary Air Injection Hose Kit
A reliable and airtight vacuum supply is critical for S38s, to ensure proper operation of the variable resonance intake, the secondary air injection pump, and the fuel pressure regulator. A majority of S38 cars need the vacuum system addressed, and unfortunately, a growing number of the vacuum supply components are no longer available from BMW.
As always, Angry Ass has you covered. We’ve assembled a complete kit to take the guess work out of maintaining this vital system, while also providing some durability upgrades. We've replaced the failure prone stock rubber hose with upgraded woven vacuum hose. To further improve durability we replace the plastic "L" and "T" fittings with stainless steel parts to ensure a lifetime of service. We also include upgraded abrasion protection which is no longer available from BMW as well as more durable hard line for the secondary air injection system.
NOTE: Vacuum reservoir is now an option and can be selected below.
