Ignition Coil & Iridium Spark Plugs for Audi A4 Quattro (2009) 3.2L V

Direct Replacement Ignition Coils & Iridium Spark Plugs for Audi A4

Restores optimal combustion and eliminates misfires by replacing failing ignition coils and worn spark plugs with a complete, high-performance spark delivery system.

The Stock A4 Ignition Shortcomings

The factory Audi 3.2L FSI V6 engine is notorious for localized heat soak around the cylinder heads, which degrades the internal epoxy and wiring insulation of the OEM ignition coils over time. Additionally, standard factory spark plugs experience rapid electrode wear under the high-compression demands of the direct-injection (FSI) system. This dual degradation leads to increased electrical resistance, weak spark blow-out under heavy engine load, rough idling, hesitation during acceleration, and inevitable P0300-series misfire trouble codes.

The Engineering Solution

This comprehensive ignition service kit resolves OEM vulnerabilities by utilizing advanced materials to ensure consistent voltage output. The ignition coils feature upgraded copper windings and high-temperature epoxy, specifically designed to withstand the severe thermal cycling inherent in the B8 engine bay. Paired with iridium-tipped spark plugs, the system provides a highly concentrated, high-intensity spark that requires lower firing voltage. The iridium center electrode maintains precise gap specifications over extended mileage, maximizing combustion efficiency in the complex FSI environment. This results in smoother power delivery, restored engine responsiveness, stabilized fuel economy, and reliable performance without the risk of pre-ignition.
