Ignition Coil and Iridium Spark Plugs for Kia Soul (2020-2021) 1.6L

Direct-Fit Ignition Coil & Iridium Spark Plug Kit for 2020-2021 Kia Soul

Direct Replacement Ignition Set: Delivers high-dielectric spark energy and precise flame propagation to restore combustion efficiency across the entire engine operating range.

The Stock Soul Coil Degradation

Factory ignition coils and plugs on the high-compression, direct-injected 1.6L engine are exposed to severe under-hood thermal cycles. Over time, factory epoxy potting experiences micro-cracking, internal secondary winding resistance increases, and ground electrodes erode. This thermal fatigue leads to dielectric breakdown, spark scatter under boost, rough cold-start idling, hesitation under load, and intermittent misfire fault codes.

The Engineering Solution

This comprehensive ignition service kit eliminates secondary circuit breakdown by pairing four high-output coil-on-plug assemblies with four premium fine-wire iridium spark plugs. The coils feature heavy-duty internal copper windings, durable thermoplastic housings, and high-temp silicone boots that insulate against voltage arcing. Matched with erosion-resistant iridium center electrodes, this package lowers required breakdown voltage, stabilizes spark delivery under high cylinder pressures, and provides reliable combustion efficiency.
