• Restoring consistent spark delivery during routine ignition system service
• Supporting maintenance on 1982-1986 Toyota Celica and 1983-1988 Toyota Cressida models

Installation Notes and Tips

Verify engine application before installation and match each wire to the correct cylinder routing. Inspect distributor cap, rotor, and spark plugs at the same time, since worn ignition components can shorten wire life and affect performance. Route the wires away from hot exhaust surfaces and secure them in the original separators or retainers where applicable.
