Detailed Product Information

The Denso 4 Boots line focuses on OE replacement coverage for ignition service parts that need to match the original design closely. For vehicles such as the Ford Focus, Ford Escape, Mazda 3, Mercury Mariner, and Ford Transit Connect, this boot kit supports a clean ignition connection between the coil and spark plug while maintaining the original fitment profile. If you are cross-shopping Denso 671-4283 for a Ford Ranger ignition coil boot replacement or Mazda Tribute ignition boot service, this part is built for the same application family.

This part cross-references CARQUEST 35-4159 and NGK CPB-FD007 for the same application.

What It Helps Address

• Cracked or heat-aged ignition coil boots
• Misfire concerns caused by poor boot insulation
• Moisture intrusion at the coil-to-spark-plug connection
• Hard starting or rough running linked to worn boots
• Loss of ignition performance from deteriorated boot material

Installation Notes and Tips

Verify engine and ignition coil application before ordering, since fitment varies by year and model. Compatible With 2003-2011 Ford Focus, 2005-2008 Ford Escape, 2010-2013 Ford Transit Connect, 2008 Ford Ranger, 2005-2008 Mercury Mariner, 2004-2005 Mazda 3, and select Mazda Tribute and Mazda 3 applications listed in the fitment data. Inspect the coil, spark plug, and surrounding ignition components during service to confirm the source of the fault before installation.

Quality Assurance

Denso First Time Fit COP boot sets are engineered to match factory-installed boots in form and performance, with construction that meets or exceeds OE/OES standards. That OE-focused approach supports consistent fitment for ignition service on Ford Focus, Mazda 3, and related applications.
