Ignition Coil + Spark Plugs for BMW X5 (2017-2018) 3.0L

Direct-Fit OEM-Replacement Ignition Kit for 2017-2018 BMW X5 (F15)

What it Does: The ignition coil and spark plug kit replaces deteriorated factory ignition hardware on the 2017-2018 BMW X5 3.0L to eliminate cylinder misfires, smooth rough idle, and restore consistent combustion efficiency.

The Stock BMW X5 N55 Ignition Breakdown

The turbocharged 3.0L N55 inline-six engine operates under elevated cylinder pressures and severe thermal stress. Factory coil packs located directly above the cylinder head endure continuous heat soak cycles, leading to degraded internal copper windings, micro-fracturing in the dielectric potting, and breakdown of the silicone spark plug boots. Over time, this degradation increases secondary resistance, resulting in spark blowout under boost, hesitation, fuel trim drift, and DME misfire fault codes.

The Engineering Solution

This comprehensive service kit pairs six direct-fit coil-on-plug ignition coils with six precision Bosch Platinum spark plugs to establish factory-spec arc stability. Built with high-dielectric epoxy potting and heavy-duty silicone boots, these coils resist high-voltage flashover and thermal fatigue. Matching fresh platinum electrodes restores factory quench characteristics and proper spark kernel development, meeting or exceeding OEM reference 12138616153 and UF667 specifications without altering factory electrical draw.

Frequently Asked Questions & Fitment Warnings

Does this fit the F15 X5?

Yes, this is a direct fit for the 2017-2018 BMW X5 equipped with the N55 3.0L inline-six engine. This kit does not fit 4.4L V8 (N63/S63), 2.0L hybrid (xDrive40e), or 3.0L diesel (xDrive35d) models.

Should I replace spark plugs and ignition coils together?

Yes, replacing plugs and coils concurrently standardizes secondary ignition resistance across all six cylinders, preventing premature coil burnout and eliminating intermittent misfires.

The BMW Precision Standard

Engineered to satisfy demanding European DME parameters, this system maintains strictly controlled primary and secondary resistance values to protect catalytic converters, avoid CEL shadow codes, and preserve smooth inline-six engine balance.
