Ignition Coil and Iridium Spark Plugs for Fiat 500L (2014-2020) 1.4L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2014-2020 Fiat 500L

What it Does: Replaces degraded factory coil packs and worn spark plugs to eliminate misfires, stabilize idle fluctuations, and restore factory ignition efficiency.

The Stock 500L Ignition Weakness

The 1.4L MultiAir Turbo engine operates under high cylinder pressures and compact under-hood thermal conditions. Over time, OEM coil pack insulation and boot silicone suffer dielectric breakdown from continuous thermal cycling. This leads to internal resistance drift, high-rpm spark blowout under boost, and recurrent P0300–P0304 misfire trouble codes.

The Engineering Solution

This complete 4-cylinder ignition kit is built with premium-grade internal copper primary and secondary windings encased in high-dielectric epoxy to resist thermal cracking and voltage leakage. Paired with direct-gap fine-wire iridium spark plugs, the assembly lowers ignition voltage demand, promotes rapid flame kernel expansion, and ensures stable combustion across the entire rev range.
