• Silicone spark plug boot material for heat resistance and flexibility
• Female spark plug end terminal type
• Female distributor/coil end terminal type

• Built to meet or exceed OE/OES standards

Product Details

The Denso First Time Fit line is engineered as an OE-style replacement line for ignition service, and this 671-4084 wire set follows that approach with factory-matched construction details. The 7mm design, silicone boots, and female terminals support proper connection at the spark plug and coil/distributor ends, helping maintain consistent ignition transfer in vehicles such as the Chrysler PT Cruiser and Dodge Neon. This part cross-references NAPA Mileage Plus 6714084 for the same application.
