Product Details

The Denso 7mm product line focuses on factory-style ignition components that match original equipment specifications. Part number 671-8162 follows that approach with OE-matched form and performance characteristics, making it a practical replacement for worn ignition leads on 2004-2005 Cadillac CTS, 2012-2015 Chevrolet Camaro, 2003-2004 Chevrolet Corvette, and 2004 Pontiac GTO. This part cross-references ACDelco 748MM for the same application.

As an ignition wire set, this component helps maintain consistent spark delivery from the coil or distributor end to the spark plug end. The silicone boot construction and 180-degree spark plug end design support proper connection and routing in applications where factory-style fitment matters.

What It Is Used For

  • Replacing cracked, heat-aged, or brittle ignition wires

  • Correcting poor terminal contact at the spark plug or coil end
  • Addressing routing issues caused by damaged or incorrect-length wires
  • Servicing OE-style ignition systems on Cadillac CTS, Chevrolet Camaro, Chevrolet Corvette, and Pontiac GTO

Installation Notes

Verify engine application and wire routing before installation. Match each lead to the correct cylinder and confirm the female terminals seat fully at both ends. Inspect spark plug condition, coil towers, and boots during service to avoid repeat ignition faults. Use the vehicle-specific routing path to prevent heat damage and crossfire.
