Ignition Coil Spark Plugs for Honda Accord (2000-2007) 3.0L

Direct-Fit Ignition Coil & Iridium Spark Plug Kit for 2000-2007 Honda Accord (CG/CM)

What it Does: The Ignition Coil and Iridium Spark Plug Kit refreshes the ignition system on the 2000-2007 Accord 3.0L to eliminate cylinder misfires, stabilize rough idle, and restore crisp throttle response.

The Stock Honda Accord Ignition Breakdown

Factory ignition coils on the J30A V6 endure extreme thermal stress recessed deep inside the spark plug tubes of the aluminum cylinder head. Over time, persistent thermal cycling breaks down the internal epoxy insulation and hardens the silicone boots, causing high-voltage dielectric breakdown and spark leakage to ground. This failure manifests as P0300–P0306 diagnostic trouble codes, poor fuel economy, and power hesitation under load. Concurrently, worn factory plugs develop excessive electrode gaps, overworking aged coils and accelerating complete coil-pack failure.

The Engineering Solution

This comprehensive tune-up kit replaces the entire secondary ignition chain with six heavy-duty coil-on-plug (COP) units and six fine-wire iridium spark plugs. The replacement coils feature heat-resistant silicone boots and high-grade copper windings sealed in durable epoxy resin to prevent arching under full load. Matched with fine-wire iridium spark plugs, the system requires significantly lower arc voltage to initiate combustion, ensuring consistent flame-kernel propagation, improved fuel burn, and extended service life without gap erosion.

Frequently Asked Questions & Fitment Warnings

Does this fit the CG/CM Accord?

Yes, this is a direct bolt-on fit for the 2000-2007 Honda Accord equipped with the J30A 3.0L V6. This kit does not fit 2.4L 4-cylinder or Hybrid models.

Should dielectric grease be used during installation?

A light application of dielectric grease inside the plug boots is recommended to prevent moisture intrusion and prevent the boots from baking onto the spark plugs.
