Ignition Coil and Iridium Spark Plugs for Honda Fit (2015-2020) 1.5L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2015-2020 Honda Fit

What it Does: Restores factory combustion efficiency, eliminates cylinder misfires, and resolves rough idle by replacing worn ignition coils and degraded spark plugs with matched OEM-spec components.

The Stock Fit Ignition Breakdown

The direct-injected L15B1 engine operates under high cylinder pressures and elevated thermal cycles, causing factory pencil coils to experience dielectric breakdown in the internal epoxy and secondary windings over time. Concurrently, electrode wear on factory plugs increases the required firing voltage, forcing heat-stressed coils to overwork. This leads to carbon tracking, hesitation under load, poor fuel economy, and standard P0300-P0304 DTC misfire codes.

The Engineering Solution

This complete ignition overhaul kit features four high-dielectric pencil ignition coils engineered with high-conductivity copper windings and heat-resistant thermoplastic housings to prevent secondary voltage leakage. Paired with four ILZKAR8H8S laser-welded iridium spark plugs, the fine-wire center electrode lowers ignition voltage demand, stabilizes combustion under direct injection pressures, and delivers superior resistance to spark erosion and thermal fouling.
