    I have a compression tester. I need to compare hose threads with my spark plugs. What size adapter would I need for a 99- 2.4 litre. I was told they were 14mm so I would need a 14mm adapter. Can anyone confirm or clarify ? No one ever specify's what the millimeter or TPI is.

    Thanks

    14x1.25. Any decent compression tester should have that adaptor included as it's been a VERY common plug size for >20 years now.
