The Standard Ignition Relay RY-779 is a direct-fit replacement for the listed applications. It fits many vehicles, among them the 2002-2003 BMW M5 and the 1994-1999 BMW M3. Standard Ignition lists it as an air pump relay. It is also cataloged as a fuel injection relay, fuel pump relay, horn relay and secondary air injection relay.
A relay lets a low-current control signal switch a higher-current circuit on and off. If a failed relay is why the circuit it controls won't switch on or works only intermittently, this unit replaces it.
- Composite housing: The relay uses a high-quality composite housing designed to stand up to harsh temperatures and demanding under-hood conditions.
- Certified manufacturing: It is produced at TS16949 and ISO9001 certified facilities.
- OE ignition background: Standard Ignition is a global manufacturer of original equipment ignition products. It maintains quality control through the whole process, from components to the finished relay.
