Ignition Coil and Iridium Spark Plugs for Audi S3 (2008-2010) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2008-2010 Audi S3

Complete Ignition Refresh Kit: Restores high-rpm spark energy, eliminates boost-induced misfires, and stabilizes cylinder combustion across the turbocharged 2.0L TFSI engine.

The Stock S3 High-Boost Ignition Vulnerability

The transverse EA113 engine in the S3 operates under aggressive boost pressures, generating substantial cylinder head temperatures. Over time, OEM coil packs succumb to thermal breakdown and micro-cracking in the primary epoxy potting. This dielectric degradation leads to voltage leakage, inconsistent dwell timing, spark blowout under load, and sudden misfire fault codes. Worn factory spark plugs compound the problem by eroding electrode gaps, increasing the secondary voltage demand beyond what degraded stock coils can deliver.

The Engineering Solution

This direct-replacement kit pairs four reinforced coil-on-plug assemblies with four premium fine-wire iridium spark plugs. Built with high-grade internal copper windings and high-temperature elastomeric boots, the coils provide reliable insulation against heat soak and deliver steady secondary kilovolt output. The ultra-dense iridium electrode centers offer exceptional thermal endurance and lower required arc voltage, ensuring crisp ignition propagation, smooth idle stability, and uncompromised throttle response under peak boost.
