Product Details
This Denso 671-4164 spark plug wire set is engineered for direct-fit ignition service on the Toyota MR2. The 5mm wire design, 105-degree spark plug boots, and OE-matched terminal configuration help maintain proper routing and secure connections at the spark plugs and distributor or coil end. Denso’s First Time Fit line focuses on factory-style replacement parts that match the original application without changing the vehicle’s ignition layout.
Fits 1991 Toyota MR2, N/A. Fits 1992 Toyota MR2, N/A, to 1/92; 5mm.
Common Issues This Part Addresses
- Misfires caused by worn or deteriorated ignition wires
- Hard starting from weak spark delivery
- Rough idle related to damaged wire insulation or boot wear
- Intermittent ignition performance from loose or corroded terminals
- Routing problems in the Toyota MR2 engine bay when original wire shape no longer holds
Installation Notes
Match each wire to the original routing before removal, then transfer one lead at a time to avoid cross-connection. Confirm the 105-degree spark plug boot orientation and the female spark plug terminal type during installation. Verify fitment against the vehicle build date for the 1992 Toyota MR2, since this listing applies to vehicles built to 1/92.
Quality Assurance
Denso states that First Time Fit ignition wire sets are built to OE/OES standards and are intended to match factory-installed wire sets in form, fit, color, and performance. That makes Denso 671-4164 a direct replacement choice for Toyota MR2 ignition service where original-style fitment matters.
