Checking your engine's compression should be a routine part of any major tune-up. Don't spend endless hours and money tuning your car only to find out your engine needs repairs. Kit includes large 2 1/2" shock resistant gauge, built-in pressure relief valve, to permit compression retesting without gauge removal. Also included is a special 12mm adapter for all 4-valve engines. Fits all BMW cars, diesel excluded.
