The MSD IGNITION 8.5MM Wire Set for 79-92 Toyota 22R trucks is a super conductor spark plug wire kit designed to restore and enhance ignition performance in classic Toyota four-cylinder applications. This factory-style wire set features MSD's proven spiral core construction with 8.5mm conductor diameter, delivering reliable spark transmission while maintaining compatibility with original equipment boot and terminal designs.
The 8.5mm super conductor core provides superior electrical conductivity compared to standard carbon-core wires, reducing voltage drop across the ignition circuit and ensuring consistent spark energy at each cylinder. The spiral core construction minimizes electromagnetic interference and cross-firing between adjacent cylinders, critical in tight engine bay configurations like the 22R. Red insulation facilitates quick visual identification of wires during maintenance, and the factory-style boots and terminals guarantee proper seating on both the spark plugs and distributor cap without modification to original hardware.
This wire set suits truck owners performing routine ignition maintenance, engine rebuilds, or performance tuning on 1979–1992 Toyota pickup models equipped with the 22R four-cylinder engine. Whether addressing fouled original wires, upgrading an aging ignition system, or establishing baseline performance before further modifications, the MSD 31949 provides documented OEM compatibility without requiring distributor or coil changes. The complete kit arrives ready to install with all four cylinders covered.
MSD Ignition has established itself as a manufacturer of aftermarket ignition components trusted by mechanics and enthusiasts working with vintage and classic vehicles. The 8.5MM Wire Set represents the company's mid-range wire offering, positioned above basic carbon-core replacements but designed around proven factory specifications rather than radical performance claims, making it a practical choice for straightforward restoration or reliable daily-driver maintenance.
