Mishimoto Ignition Coil Set 8 Pack 2011-2015 BMW 550i 4.4L

Provides reliable ignition spark — Mishimoto Ignition Coil Set 8 Pack for 2011-2015 BMW 550i 4.4L, restoring consistent spark delivery to help prevent misfires and maintain engine drivability and reliability.

The ignition coil set addresses one of the four basic requirements for engine operation: spark. Mishimoto-designed coils are intended to replace worn or weak coils so the ignition system can deliver consistent high-voltage pulses to each cylinder. Ensuring a strong, repeatable spark is a necessary step before pursuing any additional engine performance upgrades.

Why this matters: a weak or failing ignition coil can cause misfiring and degraded engine performance. Replacing the coil set restores proper ignition timing and combustion stability, helping the engine run as intended and reducing diagnostic ambiguity when evaluating fuel, air, or compression issues.

Application: This kit is specified for the 2011–2015 BMW 550i with the 4.4L engine and is supplied as an 8-pack to service all cylinders in one maintenance step.

Brand and quality note: Mishimoto is recognized in motorsports and performance circles for producing engineered replacement components intended for reliability and repeatable operation under demanding conditions.

Recommended use: Install the full 8-pack when any cylinder shows signs of ignition-related faults or when performing preventive maintenance prior to performance modifications. Replacing all coils together ensures uniform performance across the engine and simplifies troubleshooting.
