- Is this set a direct replacement for my car?
- It fits the Chrysler, Dodge and Volkswagen applications Champion lists for part 9440. Check your engine code and the number stamped on your current plugs before ordering, since heat range and thread length must match.
- Do I need to gap these plugs?
- Check the gap before installing. Iridium plugs are often pre-gapped, but the gap should match your engine's spec, and the fragile tip bends easily if forced.
- How long do iridium plugs last?
- Iridium plugs typically last far longer than copper plugs, often around 60,000 to 100,000 miles depending on the engine. Follow the interval in your owner's manual.
- How many plugs are in the set?
- The set contains four plugs, enough for a four-cylinder engine. Six- and eight-cylinder engines need two sets.
- Should I use anti-seize on the threads?
- Follow the plug maker's and your manual's guidance. Many iridium plugs have a coated thread and need no anti-seize; over-torquing is the bigger risk.
