Product Details

Denso First Time Fit COP boot sets are engineered to mirror the original factory boot design, helping maintain proper ignition coil connection and reliable spark transfer. The Denso 671-4273 is a direct ignition coil boot kit for select Volkswagen Golf, Jetta, Beetle, and Passat models, as well as Audi A4 and A4 Quattro applications. If you need a Denso 671-4273 replacement for a 2000-2005 Volkswagen Golf or Jetta, or a 1997-1999 Audi A4, this part is built for the same application profile as the original equipment boot set.

This part cross-references CARQUEST 35-6204 and NGK CPB-EU005 for the same application.

Common Issues This Part May Address

• Cracked or heat-damaged ignition coil boots
• Misfire caused by worn boot insulation
• Weak coil-to-spark plug connection
• Moisture intrusion at the ignition boot
• Hard starting related to degraded ignition boot condition

Installation Notes and Tips

Verify the vehicle application before installation by matching the year, make, and model to the fitment list. Inspect the ignition coil and spark plug condition during service, and replace any damaged components as needed to restore proper ignition performance. Confirm the female terminal connection seats fully and that the boot length and shape match the original part.

Quality Assurance

Denso First Time Fit components are produced to OE-style standards and are intended to match factory fit and performance characteristics. The 671-4273 is designed as a direct replacement for select Volkswagen and Audi ignition systems.
