Detailed Description

This Denso First Time Fit ignition wire set is engineered as an OE replacement for vehicles that require a 5mm ignition lead design. The 671-4144 wire set is listed for 1997-2001 Toyota Camry, 1999-2001 Toyota Solara, and 1998-2000 Toyota RAV4, making it a focused choice for owners searching for a Toyota Camry spark plug wire set, Toyota Solara ignition wire replacement, or Toyota RAV4 spark plug wire set by part number 671-4144. Denso’s First Time Fit line is built to mirror factory-installed dimensions and connection style so the wires seat correctly at the spark plug and distributor/coil ends.

This product line is positioned as an OE-style replacement solution for drivers who want the same basic form and performance characteristics as the original wire set. The 105-degree spark plug boot helps with routing where clearance is limited, while the 5mm insulation diameter supports a factory-like fit in the engine compartment. This part cross-references Bosch 09475 and NGK TE58 for the same application.
