Product Details

This Denso First Time Fit ignition wire set is engineered as a direct replacement for OE/OES ignition leads. The 7mm wire diameter supports factory-style fitment, while the 90-degree spark plug boots help maintain proper routing in compact engine compartments. Denso 671-4174 is a practical choice for drivers servicing ignition systems on a Honda Accord or Honda Prelude where accurate terminal style and OE-like construction matter. This part cross-references NGK HE57 and HE62 for the same application.

What It Helps Address

• Misfires caused by worn or deteriorated spark plug wires
• Hard starting related to weak ignition transfer
• Rough idle from inconsistent spark delivery
• Voltage leakage from cracked or aged wire insulation
• Routing issues when replacing damaged OE-style ignition leads

Installation Notes

Verify engine application before installation and route each lead to match the original layout. Confirm the female spark plug terminals and male distributor/coil end terminal type match the vehicle’s ignition system. For Honda Accord and Honda Prelude service, compare the existing wire lengths, boot angles, and terminal positions before removal to help ensure correct placement. Denso 671-4174 is listed for 1990-1997 Honda Accord and 1992-1996 Honda Prelude models with 7mm wire specification.
