Product Details

Denso 671-6126 is a spark plug wire set engineered for Jeep ignition systems that require a 7mm wire profile and OE-style terminal configuration. The wire set uses silicone boots and a combination of angled and straight spark plug ends to help maintain proper routing and secure connection at the plug and distributor or coil end. For Jeep Wrangler, Cherokee, and CJ-series vehicles, this type of ignition wire set helps preserve consistent spark delivery and factory-style fitment.

This part cross-references ACDelco 16-806E and Bosch 09279 for the same application.

Installation Notes and Tips

Match each lead to the correct cylinder and follow the original routing path to avoid crossfire or heat damage. Confirm the distributor/coil end and spark plug end terminal types before installation, and verify that the 90-degree boots clear nearby components where needed. For Jeep CJ5, CJ7, Wrangler, Cherokee, and J10 applications, compare the existing wire lengths and routing layout before removal.
