It lets you compare spark plug performance quickly and clearly, so you can assess plug health without guesswork. Built for both professionals and DIYers, the SP20 emphasizes speed, simplicity, and real-world usefulness in everyday maintenance tasks.\u003c\/p\u003e\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003eWith a simple, one-button workflow, you insert two plugs into the dual sockets and press to view results. No complex setup or RPM tuning is required. The dual-port design enables side-by-side testing, making it easier to spot differences between a new plug and an older one under simulated operating conditions.\u003c\/p\u003e\n\u003ch3\u003eRealistic testing with practical insights\u003c\/h3\u003e\n\u003cp\u003eThe SP20 simulates ignition conditions around 2000 RPM, allowing you to observe ignition strength and timing feel in a controlled setting. This helps you form a practical sense of whether a plug might be contributing to misfires, hard starts, or rough idling—without replacing parts prematurely.\u003c\/p\u003e\n\u003ch3\u003eSafety, compatibility, and care\u003c\/h3\u003e\n\u003cp\u003eA built-in, clear protective cover provides shock protection and contains sparks during testing, supporting safer operation in garages, repair shops, or on-site service.
