What It Helps Address

• Misfires caused by worn or heat-damaged plug wires
• Hard starting related to weak ignition transfer
• Rough idle from deteriorated wire insulation or terminals
• Voltage leakage from cracked boots or aging wire jackets
• Service issues on Toyota MR2 ignition maintenance

Installation Notes and Tips

Before installation, compare the routing and terminal ends to the original Toyota MR2 wire set to confirm correct cylinder placement. Apply the included dielectric grease to the boot interiors where appropriate, and make sure each connection seats fully on the spark plug and ignition coil or distributor terminal. Inspect nearby ignition components for wear so the new wires are not installed over damaged hardware.
