Features

• •【CHECK SPARK PLUG ISSUES BEFORE REPLACING PARTS】Hard starts, rough idle, misfires, or weak acceleration can be difficult to trace. This spark plug tester helps you visually check spark performance before replacing parts, making it easier to identify weak, aging, or faulty spark plugs during routine maintenance
• •【DUAL-SOCKET DESIGN FOR SIDE-BY-SIDE COMPARISON】Test two spark plugs at the same time and compare spark strength and stability under the same simulated working condition. This dual-port spark tester helps you compare old vs. new plugs, spot weak spark output, and make more confident repair decisions
• •【SIMPLE ONE-BUTTON TESTING】No complicated setup or RPM adjustment required. Insert the spark plugs, close the protective cover, press the button, and observe the spark through the clear window. Easy to use for DIY users, home garages, small engine maintenance, and professional repair shops
• •【CLEAR SAFETY COVER FOR BETTER PROTECTION】The built-in transparent cover helps isolate the high-voltage test area while allowing you to clearly observe spark activity. It helps reduce accidental contact during testing and keeps the process cleaner and safer when used properly
• •【WIDE 12V GASOLINE ENGINE APPLICATIONS】Compatible with most standard spark plugs for 12V gasoline engines, including cars, motorcycles, ATVs, lawn mowers, generators, and other small gas engine equipment. Suitable for spark plugs with an insulator diameter up to 13mm
