Use the adjustable RPM dial to simulate engine conditions and observe how each plug responds. The dial covers a wide range up to 6000 RPM, allowing you to tailor the test to your engine’s behavior. In many cases, a setting around 2000 RPM provides a meaningful demonstration of plug performance without excessive cranking.\u003c\/p\u003e\n\n\u003ch3\u003eGetting the Most From SP02\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eTest two plugs at once to compare response time and consistency\u003c\/li\u003e\n  \u003cli\u003eSet the RPM to match typical operating conditions for your engine\u003c\/li\u003e\n  \u003cli\u003eLook for consistent response between plugs to guide replacement decisions\u003c\/li\u003e\n  \u003cli\u003eKeep the tester clean and stored in its protective case when not in use\u003c\/li\u003e\n  \u003cli\u003eConsult support if you’re unsure about plug compatibility or setup\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eCompatibility \u0026amp; Safety\u003c\/h3\u003e\n\u003cp\u003eSP02 is designed for most 12V gasoline engines with insulator diameters under 12.2 mm and lengths between 33 and 43 mm.
