SPARK PLUG PRESSURE TESTER

This spark plug tester could help you identify a potential failure due to the center electrode becoming dislodged from the porcelain ahead of time.

Simply install all 16 spark plugs into the base and spray a soapy water mix onto the plugs. Place the containment shield on top and secure it for safe operation. Connect to your shop air or CO2, build pressure, and inspect for any leaks through the front window.
