Ignition Coil and Iridium Spark Plugs for Audi Q7 (2007-2010) 3.6L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2007-2010 Audi Q7

Primary Function: Restores factory secondary ignition performance and consistent spark kernel generation for the 3.6L FSI VR6 engine.

The Stock Q7 Ignition Breakdown

The compact cylinder head geometry of the 3.6L VR6 traps significant thermal energy within the coil tunnels. Over time, heat cycles degrade factory coil-on-plug silicone insulation, inducing dielectric breakdown and internal resistance drift in the primary windings. Coupled with electrode wear on older plugs, this impedance spike leads to intermittent high-load misfires (DTC P0300-P0306), unburnt hydrocarbon accumulation, unstable idle quality, and catalytic converter stress.

The Engineering Solution

This comprehensive service kit restores electrical integrity via six direct-replacement ignition coils and six fine-wire iridium spark plugs. The coil assemblies feature high-grade electrolytic copper windings and specialized vacuum-potted epoxy shielding to mitigate thermal breakdown and voltage leakage. Paired with laser-welded iridium electrode center tips, the system maintains lower ignition voltage requirements, resists carbon fouling, and delivers rapid flame propagation under direct-injection cylinder pressures.
