This CHT proge works great. Screwed right in. Worked first try - no problem. This is just like the other JPI probes the factory had installed. I used it to replace the ring probe that goes around the spark plug. There is an after-market probe that is cheaper but it requires an adapter. Im sure it would have worked, but this matches my others.
