J Perkins RC Spark Plugs for Petrol Engines

Keep your petrol-powered RC running at its best with our Spark Plugs selection, featuring trusted options for Zenoah and Stinger Engines. Whether you’re maintaining a large-scale car, boat or aircraft, choosing the right plug makes a big difference to starting, throttle response and reliability.

Use the filters to match your engine: check thread size and reach, the correct heat range for your tune, and whether your ignition requires a resistor plug. Many popular Zenoah-based setups use compact plugs such as CMR7H-style; always confirm your engine spec or ask our team. Plugs are typically pre-gapped, but it’s good practice to verify the gap and replace the washer if required. If you notice hard starting, misfires under load or sooty deposits, a fresh plug is often the quickest fix—keep a spare in your pit box.
