Product Details

The Denso First Time Fit line focuses on exact replacement characteristics, and this 671-6054 spark plug wire set follows that approach with OE-matched dimensions and terminal styles. The 7mm wire design, silicone boots, and mixed angled and straight boot configuration support proper routing on engines that use a horizontal distributor cap layout or standard 7mm ignition wire setup. This part cross-references NGK IX59 for the same application.

Common Repair Uses

• Replacing cracked or heat-damaged ignition wires
• Restoring weak spark transfer caused by worn terminals
• Correcting misfire symptoms tied to deteriorated wire insulation
• Addressing hard-start or rough-idle conditions linked to ignition wire wear
• Replacing aging OE wires on Chevrolet Astro, GMC Safari, and Chevrolet S10 applications

Installation Notes and Tips

Match each wire to its original routing before removal to avoid crossfire or interference. Confirm the distributor and spark plug terminal ends are seated fully, and verify the 90-degree boot orientation clears nearby components. On vehicles listed with a horizontal distributor cap note, follow the factory routing path closely for proper fitment.
