Overview

The NGK BPMR7A Spark Plug is a premium OEM replacement ignition component designed for a wide range of STIHL 2-stroke and 2-MIX outdoor power equipment, including chainsaws, brushcutters, mistblowers, blowers, and concrete cut-off saws. Engineered to deliver reliable spark ignition under demanding operating conditions, it plays a vital role in ensuring easy engine starting, smooth idling, and optimal power delivery.

Featuring a built-in resistor to suppress radio frequency interference (RFI) that can disrupt electronic equipment, the BPMR7A is constructed with high-grade alumina silicate ceramic insulation and a solid copper core. This design facilitates efficient heat dissipation, preventing engine pre-ignition and spark plug fouling caused by oil carbon buildup. Maintaining a clean, properly gapped spark plug helps reduce fuel consumption, minimizes exhaust emissions, and ensures dependable ignition across full-throttle operations.
