Details
[CHECK BEFORE YOU REPLACE] Compare two plugs side by side before replacing parts. This spark plug tester makes weak, inconsistent, intermittent, or no-spark performance easier to spot.
[COMPARE TWO AT ONCE] Test a suspect plug against a known-good or new plug under the same conditions. The dual-port spark plug checker gives you a clear visual reference.
[SIMPLE ONE-BUTTON TESTING] Install two compatible plugs, connect power, secure the cover, then press and hold the button to compare. No complicated setup or extra adjustments—simple for DIYers and garage use.
[CLEAR SAFETY COVER] This automotive spark plug tester operates only when the protective cover is properly secured. The clear cover lets you watch both plugs while keeping the test area covered.
[FOR CARS, MOTORCYCLES & SMALL ENGINES] Works with compatible spark plugs from cars, motorcycles, ATVs, lawn equipment, generators, and other gasoline engines. If your engine uses one spark plug, use a same-type known-good or new plug in the second port. Powered by 110–120V AC. Plugs 34 mm (1.34 in) or longer are recommended; very short plugs may not fit properly.
