Ignition Coil and Iridium Spark Plugs for Honda Fit (2006-2008) 1.5L

Direct-Replacement Ignition Coil and Iridium Spark Plug Kit for 2006-2008 Honda Fit

Primary Function: Restores factory secondary ignition output, eliminating misfire codes and erratic idle on high-mileage L15A1 powertrains.

The Stock Fit Ignition Breakdown

Factory coil packs on the first-generation Fit operate in a tight, high-heat pocket behind the cowl. Over repeated thermal cycles, OEM epoxy potting degrades and dielectric boots harden, causing secondary voltage leakages, carbon tracking, and intermittent cylinder misfires (P0301–P0304) under load. Paired with aged, high-gap plugs, the excessive electrical resistance accelerates coil driver failure inside the ECU.

The Engineering Solution

This complete 4-cylinder tune-up kit utilizes reinforced coil-on-plug assemblies wound with premium-grade internal copper wiring and sealed in high-dielectric epoxy to resist breakdown under sustained underhood temperatures. Direct-fit blade terminals ensure low-resistance connectivity without harness modification. The included fine-wire iridium spark plugs feature laser-welded center electrodes that lower the required firing voltage, providing stable spark kernel propagation, crisp throttle response, and dependable combustion efficiency across the rev range.
