Spark Plug Hole Thread Size

Whats up everybody.

Anybody know what size of plug I need when performing a compression test, or does the right size that fits into the spark plug hole come with the tester?

Thanks

Most testers come with several adapters, so get one of those.

Alright cool, does anybody know where I can get a tester at?
Can it be rented at an auto parts store?

Wal-mart maybe? haha

Alright just to let people know, the size when buying a compression tester is 18mm of which will fit the Rx-7's spark plug hole. This size is standard with most compression testers.

I got my tester at Sears for $25. Not bad, but I haven't tried it yet.
