Ignition Coil and Iridium Spark Plugs for Honda Fit (2009-2013) 1.5L

Direct-Fit Ignition Coil & Iridium Spark Plug Service Kit for 2009-2013 Honda Fit

Primary Function: Restores complete combustion efficiency and eliminates cylinder misfires by replacing heat-degraded factory ignition coils and worn plugs with an integrated, high-conductivity service pack.

The Stock Fit Secondary Ignition Breakdown

On the second-generation GE8 chassis, the transverse 1.5L engine packaging traps ambient radiant heat around the rear-mounted coil pack boots. Continuous thermal cycling degrades the factory silicone insulation and internal potting epoxy, leading to high-voltage dielectric breakdown and micro-arcing. As resistance increases, spark energy drops, triggering intermittent hesitation, rough idle, P0300-P0304 misfire diagnostic trouble codes, and unburnt hydrocarbon loading on the catalytic converter.

The Engineering Solution

This service kit restores primary and secondary ignition stability by pairing heavy-duty coil packs with laser-welded fine-wire iridium center electrode spark plugs. The replacement coils utilize vacuum-potted epoxy resin and high-grade copper windings to isolate voltage spikes and resist thermal fatigue. Paired with ultra-durable iridium spark plugs, the system requires lower striking voltage, delivers a more concentrated spark kernel, and ensures consistent ignition timing across the entire VTEC load range.
