What It Helps Address

  • Cracked or heat-aged ignition coil boots

Installation Notes and Tips

Verify vehicle application by year, make, and model before installation. Inspect the ignition coil, spark plug well, and surrounding sealing surfaces for wear or contamination before installing the new boot. For best results, replace damaged boots when servicing the ignition system on Ford Edge, Ford Focus, or Lincoln MKZ applications.

Quality Assurance

Denso First Time Fit COP boot sets are manufactured to meet or exceed OE/OES standards for construction and performance. The 671-4325 is built as an OE-style replacement for direct ignition service.
