Product Details

This Denso First Time Fit ignition wire set is engineered to mirror the original wire set used on the vehicle, helping preserve proper ignition transfer and factory-style routing. The 7mm wire diameter, angled 90-degree spark plug boots, and OE-style terminal configuration support clean installation on engines that require precise wire fitment. Part number 671-4176 is a practical replacement choice for drivers servicing older Honda Civic, Honda CRX, Honda Civic del Sol, and Acura Integra ignition systems.

This part cross-references NGK (e.g., HE53, HE64) for the same application.

Installation Notes

Match each wire to the correct cylinder and follow the original routing path to avoid crossfire or heat damage. Confirm the 90-degree spark plug boots seat fully on the plugs and verify the distributor/coil end terminals are fully engaged before starting the engine. For best results, inspect spark plugs, distributor cap, and ignition components at the same time.
