Ignition Coil & Spark Plugs for BMW 750i xDrive 750Li xDrive (2010-2012) 4.4L V8

Direct-Fit Ignition Coil & Spark Plugs for 2010-2012 BMW 7 Series

Restoring optimal spark delivery and combustion efficiency: This complete ignition service kit replaces degraded factory ignition coils and fouled spark plugs to eliminate misfires, rough idling, and hesitation under load.

The Stock 7 Series Ignition Weakness

The N63 4.4L twin-turbo V8 engine is notorious for generating extreme thermal loads within the engine bay, particularly within the deep spark plug wells. Over time, the intense heat cycle causes the factory ignition coil epoxy to degrade and the rubber boots to crack, leading to voltage leaks and arc faults. Concurrently, the OEM spark plug electrodes wear down due to high cylinder pressures and direct injection characteristics, widening the spark gap and overworking the failing coils. This cascading failure results in persistent cylinder misfires, poor fuel economy, and potential catastrophic damage to the catalytic converters if left unaddressed.

The Engineering Solution

This comprehensive ignition kit utilizes upgraded dielectric materials and reinforced housings to withstand the punishing heat soak inherent to the F01/F02 chassis layout. The precision-wound copper internal coils provide a consistent, high-energy voltage output for a complete combustion event. Paired with the platinum-tipped spark plugs, which feature superior erosion resistance and stable gap retention, the system guarantees a focused, powerful spark even under peak boost pressures. The platinum construction ensures an extended service life while resisting carbon fouling, resulting in smoother power delivery, restored throttle response, and a stable idle.
