Ignition Coil and Iridium Spark Plugs for BMW 6 Series (2006-2010) 4.8L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2006-2010 BMW 6 Series

Primary Function: Restores factory secondary ignition output and eliminates cylinder misfires across the entire N62 V8 engine block by replacing degraded coil packs and worn spark plugs.

The Stock 6 Series Thermal Degradation Weakness

The naturally aspirated 4.8-liter N62 V8 in the E63 and E64 chassis operates under extreme underhood thermal conditions. Due to tightly packaged engine bays and high cylinder head temperatures, factory ignition coil boots harden, develop micro-fractures, and experience dielectric breakdown. Simultaneously, standard copper or aged platinum plugs suffer center electrode erosion, widening the plug gap. This elevates required secondary voltage, placing excessive electrical stress on the internal coil windings and leading to intermittent high-RPM misfires, rough cold idling, unburned hydrocarbon buildup, and catalytic converter damage.

The Engineering Solution

This 16-piece complete ignition overhaul kit includes 8 direct-fit coil-on-plug assemblies engineered with high-grade internal copper windings and reinforced dielectric silicone boots to prevent voltage arcing under high-heat duty cycles. Matched with 8 fine-wire iridium spark plugs, this setup features a resilient 0.6mm iridium center electrode and ground strap engineered to withstand thermal shock and resist carbon fouling. The result is a consistent, high-energy spark curve, lower required ignition voltage, crisp throttle response, and smooth idle stability.
