Product Details

The Denso First Time Fit COP boot sets are built to mirror the original equipment boot in form, fit, color, and performance. That makes this ignition coil boot kit a practical replacement for worn or damaged coil boots on 2004-2008 Ford F-150, 2005-2007 Ford Expedition, and 2005-2007 Lincoln Navigator applications, along with other listed Ford, Lincoln, and Mercury models. If you are servicing a 2008 Ford Mustang or 2008 Lincoln Navigator, Denso 671-8164 provides an OE-style ignition boot solution for the factory coil-on-plug setup.

This part cross-references CARQUEST 35-1107 and NGK CPB-FD001 for the same application.

What It Is Used For

• Replacing cracked or heat-aged ignition coil boots
• Restoring spark transfer in coil-on-plug ignition systems
• Addressing misfire concerns tied to worn boot insulation
• Repairing ignition performance issues caused by carbon tracking or moisture intrusion
• Servicing Ford, Lincoln, and Mercury V8 ignition systems with OE-style boot fitment

Installation Notes and Tips

Verify the vehicle year, make, and model against the listed fitment before installation. Inspect the ignition coil, spark plug well, and surrounding seals for wear, contamination, or damage before installing the new boot. Clean mating surfaces and confirm the boot seats fully on the coil and spark plug to maintain proper electrical contact.

Quality Assurance

Denso states that the First Time Fit COP boot set construction meets or exceeds OE/OES standards. The 671-8164 boot kit is built to the same form and performance expectations as the factory-installed part for the listed applications.
