The Mishimoto BMW 550i Ignition Coil is a high-quality replacement designed to restore the factory performance and fuel efficiency of your 4.4L V8 engine.
Designed to eliminate the limitations of the restrictive factory fuel setup, this premium dual-pump system comes pre-loaded with two high-flowing DW420 fuel pumps.
Crank no-start conditions are ungood. It's either air, fuel, or spark. If you're not in a vacuum, then it's probably fuel or spark. Bring your ignition system back up to snuff with ignition parts like coil packs, spark plugs, spark plug wires, distributors, and more or rejuvenate your fuel system with a fresh fuel filter, fuel pump, fuel injectors, fuel rail, and everything in between from our catalog of OEM and aftermarket suppliers.
