Ignition Coil and Iridium Spark Plugs for Audi TT (2019-2020) 2.0L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2019-2020 Audi TT

What it Does: Restores factory ignition energy and combustion efficiency by replacing degraded coil packs and worn spark plugs with matched direct-fit components.

The Stock TT Ignition Breakdown

The turbocharged EA888 Gen 3 engine generates substantial cylinder pressures and under-hood thermal loading. Over time, OEM coil housings suffer thermal fatigue, leading to micro-cracking in the epoxy insulation and internal copper winding degradation. Combined with widening spark plug gaps from electrode erosion, this creates high secondary resistance, resulting in intermittent high-load misfires, erratic idle quality, and premature spark blow-out.

The Engineering Solution

This complete ignition service kit includes four high-dielectric coil-on-plug assemblies engineered with high-conductivity internal copper windings and durable blade terminals to resist thermal breakdown. Paired with fine-wire iridium spark plugs, the kit ensures low ignition voltage requirements, consistent arc stability under boost, and precise spark timing without triggering diagnostic trouble codes.
