Comp tester
Decent quality for the money,but the fittings to screw into the spark plug threads are way too short plus there isn't a one way valve on the hose so the reading isn't accurate like the hold in fittings. So it basically is only suited to be used by holding against the plug opening,not using the screw in fittings.
