Ignition Coil and Iridium Spark Plugs for Volkswagen Jetta Taos (2022-2024) 1.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Service Kit for 2022-2024 Volkswagen Jetta, Taos (A7 / MQB A1)

What it Does: The ignition coil and iridium spark plug kit replaces fatigued factory ignition components on the 2022-2024 Volkswagen Jetta and Taos to eliminate boost misfires, stabilize idle, and restore peak combustion efficiency.

The Stock Volkswagen Jetta, Taos Ignition Breakdown

The turbocharged 1.5L EA211 evo utilizes high cylinder pressures and lean-burn strategies that demand elevated ionization voltage from the secondary ignition circuit. Over time, high thermal cycling in the recessed cylinder head causes the factory epoxy insulation to crack, leading to internal dielectric breakdown and spark arcing. Simultaneously, factory spark plug ground and center electrodes erode under boost, expanding the gap beyond operational tolerance. This excessive resistance stresses the ignition driver in the ECM and induces cylinder misfires (DTC P0300-P0304), sluggish boost onset, and catalytic-converter-damaging unburnt fuel bypass.

The Engineering Solution

This comprehensive tune-up kit features heavy-duty coil-on-plug (COP) assemblies engineered with high-temperature epoxy-filled windings and durable, heat-resistant silicone boots to completely prevent secondary flashover. Paired with fine-wire iridium center electrode spark plugs, this setup dramatically lowers the required firing voltage while providing superior erosion resistance under high boost. The spark plugs arrive pre-gapped (0.695–0.805 mm) with a 12mm thread, 16mm hex, and 28mm reach to deliver precise thermal dissipation and prevent ground-strap fatigue under sustained load.

Frequently Asked Questions & Fitment Warnings

Does this fit the A7 / MQB A1 Jetta, Taos?

Yes, this is a direct fit for the 2022-2024 Volkswagen Jetta and Taos equipped with the 1.5L EA211 evo turbocharged engine. It does not fit older 1.4L TSI or 2.0L TSI EA888 engines.

What is the correct installation torque for the spark plugs?

Torque the iridium spark plugs to 15-20 N.m into the cold aluminum cylinder head without anti-seize to ensure proper heat-range transfer and prevent thread damage.
