Designed for most 12V gasoline applications, this compact tester places two plugs under identical conditions so you can detect weak or intermittent sparks, helping you pinpoint ignition problems before you replace parts.\u003c\/p\u003e\n\n\u003ch3\u003eHow does the SP02 reveal which spark plug is failing?\u003c\/h3\u003e\n\u003cp\u003eThe dual ports let you install two spark plugs and watch their arcs at the same time, making performance differences immediately visible. By running both plugs under identical simulated RPMs, you can quickly see if one plug produces a weaker or unstable spark.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eSide-by-side visual comparison of spark intensity and consistency\u003c\/li\u003e\n  \u003cli\u003eTransparent safety cover for clear observation\u003c\/li\u003e\n  \u003cli\u003eDetects intermittent or weak sparks that may not show at idle\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCan I simulate real engine conditions with this tester?\u003c\/h3\u003e\n\u003cp\u003eYes. The SP02 includes an adjustable control knob to vary the working frequency from 0 up to 6000 RPM, so you can evaluate spark behavior across low, medium, and high speed conditions.
