Ignition Coil & Iridium Spark Plugs for BMW X5 (2007-2010) 3.0L I6

OEM-Grade Ignition Coil & Iridium Spark Plugs for 2007-2010 BMW X5

What it Does: Restores factory ignition performance and eliminates misfires on the naturally aspirated N52 3.0L engine by providing a complete, high-voltage ignition system refresh.

The Stock X5 Ignition Weakness

The factory ignition coils on the E70 BMW X5 are highly susceptible to thermal degradation. Positioned atop the N52 cylinder head beneath the acoustic engine cover, the coils endure severe heat soak and constant thermal cycling. Over time, the internal epoxy resin cracks, leading to secondary winding resistance and voltage leaks. This causes rough idling, hesitation under heavy load, and P0300-series misfire codes. Additionally, as stock spark plug electrodes erode and widen, the aging coils must work harder to bridge the gap, accelerating complete ignition failure.

The Engineering Solution

This comprehensive kit resolves the N52's ignition vulnerabilities. The replacement coils utilize high-dielectric epoxy resins and precision-wound copper primary and secondary windings to ensure stable voltage output under high operating temperatures. Reinforced silicone boots seal out moisture and resist heat-induced cracking. The included premium iridium spark plugs feature an ultra-fine center electrode that requires significantly less firing voltage than standard copper plugs. This reduced electrical strain prolongs the lifespan of the ignition coils while delivering a concentrated spark for complete combustion, stabilizing fuel efficiency and smoothing power delivery.
