Product Details

The Denso 671-6068 spark plug wire set is part of the First Time Fit line, a product line focused on direct OE-style replacement for ignition service. It is built with 7mm insulation and silicone boots to match original routing and connection requirements on vehicles that use female terminals at both ends. This makes it a practical choice for restoring ignition wire integrity on applications such as the Chevrolet Blazer, GMC Jimmy, and GMC Sonoma, where correct boot angle and terminal style matter for proper fitment.

This part cross-references ACDelco 746KK and Bosch 09791 for the same application.
