2005 Mustang 4.6V8 compression tester?
 

Hey everyone,

My buddies having trouble finding a compression tester that fits into his 4.6 V8, he’s bought 3 already and none of them fit. Do you guys have any leads on one? I would appreciate it. Thanks!

I used the cheap kit from harbor freight. None of the screw in adapters fit, but the one with a rubber seal that you hold down while cranking did, you definitely need 2 people to test it that way though.
I should say mine is a 2008 with the new heads and different plugs...
