Product Details

Denso 671-6256 is part of the First Time Fit COP boot set line, which is engineered to mirror the original boot configuration used on the vehicle. That makes it a practical choice for drivers and technicians replacing worn ignition coil boots on 2001-2006 Hyundai and Kia models, including Hyundai Santa Fe, Hyundai XG300, Hyundai XG350, Kia Amanti, Kia Sedona, and Kia Sorento. This part cross-references NGK CPB-K004 and CARQUEST 35-6220 for the same application.

As a direct ignition coil boot kit, this component supports proper coil-to-spark delivery when the original boots are cracked, hardened, or contaminated. The Denso 671-6256 is intended for service work where OE-style fit and consistent boot construction matter.

What It Helps Address

• Misfires caused by deteriorated ignition coil boots
• Cracked or heat-damaged boot insulation
