Bring back a strong, reliable spark with the Champion Spark Plug, part number 22. It serves as a direct-fit replacement for a wide range of vintage applications, including the 1962-1968 AC Shelby Cobra, 1966-1968 Ford Bronco, 1964-1969 Ford Mustang, 1958-1970 Ford Fairlane, 1965-1972 Ford LTD and the 1967 Mercury Cougar — one of 65 listed Ford, Mercury, Edsel, AC and DeTomaso applications (see the Buyer's Guide tab for the full list).
Core job: bridges the electrode gap to ignite the compressed air-fuel mixture in the combustion chamber, delivering the spark the engine needs to start and run.
Signs it may be time to replace: hard starting, rough idle, engine misfires, hesitation on acceleration or reduced fuel economy — if a worn plug is the cause, this replaces it.
Quantity: engines use one plug per cylinder, so order the number your engine requires for a complete tune-up.
Because a fouled or worn plug can share symptoms with ignition, fuel or compression issues, confirm the cause before replacing. Manufacturer part number 22.
Frequently Asked Questions
What does the Champion 22 spark plug do?

What vehicles does this spark plug fit?
It's listed for many classic Ford, Mercury and Edsel models plus the AC Shelby Cobra and DeTomaso Mangusta. Check the Buyer's Guide tab to confirm your year, make and model.
What are signs my spark plugs may need replacing?
Hard starting, rough idle, misfires, hesitation or reduced fuel economy can be signs. Diagnose the cause first, since ignition, fuel or compression issues can produce the same symptoms.
How many of these plugs do I need?

Should I replace all the spark plugs at once?
Replacing the full set together is good practice so every cylinder fires consistently and the engine runs evenly.
