Product Details

This Denso ignition wire set is engineered for accurate replacement on Toyota ignition systems that require the 5mm configuration. The 671-4151 part number is listed for 1992-1993 Toyota Camry, 1994-1995 Toyota Camry California models, 1994-1995 Toyota Celica except California, 1996 Toyota Camry, 1996 Toyota Celica except California through 10/95, and 1994-1995 Toyota MR2. This part cross-references NGK (e.g., TE43, TE62) for the same application.

Common Problems It Can Address

  • Misfires caused by worn or damaged ignition wires
  • Hard starting from weak spark delivery
  • Rough idle related to deteriorated wire insulation
  • Intermittent ignition performance from poor terminal contact
  • Voltage leakage from cracked or aged plug wire boots

Installation Notes

Verify engine application, emissions configuration, and wire routing before installation. Match the 5mm specification and terminal style to the original setup on the vehicle. On Toyota Camry, Celica, and MR2 applications, route each lead away from heat sources and moving components, and confirm each boot seats fully on the spark plug and coil or distributor connection.

Denso’s First Time Fit line is built as an OE-style replacement program, with construction that meets or exceeds OE/OES standards for the listed application. The Denso 671-4151 is intended to restore factory-type ignition wire performance and fitment consistency.
