Product Details

Denso’s First Time Fit COP boot line is focused on restoring the original connection profile between the ignition coil and spark plug. This matters on Nissan and Infiniti V6 applications where worn boots can affect ignition performance, especially in high-heat engine bays. Part number 671-6275 is a direct replacement option for drivers servicing 2002-2015 Nissan and Infiniti models, including the Frontier, Xterra, Pathfinder, Maxima, Murano, Altima, Quest, I35, and QX4. The 671-6275 boot kit is also listed for the Suzuki Equator.

This part cross-references NGK CPB-N002 and NAPA Mileage Plus 6716275 for the same application.

What It Helps Address

  • Cracked or heat-aged ignition coil boots
  • Misfire conditions caused by poor coil-to-plug contact
  • Moisture intrusion at the coil boot area
  • Hard starting or rough running linked to ignition boot wear
  • Loss of ignition performance from deteriorated boot material

Installation Notes and Tips

Verify engine application before ordering, since fitment varies by model year and engine configuration. Compatible With 2005-2015 Nissan Frontier, 2005-2015 Nissan Xterra, 2002-2012 Nissan Pathfinder, 2009-2012 Suzuki Equator, 2004-2009 Nissan Quest, 2002-2008 Nissan Maxima, 2003-2007 Nissan Murano, 2002-2006 Nissan Altima, 2002-2004 INFINITI I35, and 2002-2003 INFINITI QX4. Inspect the ignition coil and spark plug condition during service so the new boot seats properly and maintains a secure electrical connection.

Quality Assurance

Denso states that this First Time Fit COP boot set is engineered to match factory-installed boots and that its construction meets or exceeds OE/OES standards. That makes 671-6275 a technical replacement choice for Nissan and Infiniti ignition service.
