RC Engine Plugs: Glow & Spark Plug Range

Keep your RC engine lighting cleanly and reliably with our Plugs range. Whether you’re tuning a nitro for race pace or keeping a petrol model dependable, you’ll find glow plugs, glow starters and spark plugs all in one place.

Glow Plugs: Choose the correct heat range (hot for small-block/low nitro, medium as a great all-rounder, cold for high-nitro/high-rev setups) and the right type (standard or turbo) to match your engine’s head. Check thread and length, and keep spares—tired plugs can cause hard starting, misfires and erratic idle.

Glow Starters: From simple stick starters to units with meters and chargers, a healthy starter gives a strong, consistent glow for fast, fuss-free starts.

Spark Plugs: For petrol engines, match thread, reach and electrode style as specified for your engine to maintain crisp throttle response and reliable running.

We hold large stocks for quick dispatch, with next day delivery available across the UK. Not sure which plug you need? Our knowledgeable, friendly customer service team are on hand to help you choose the right part for your engine and fuel. Explore Glow Plugs, Glow Starters and Spark Plugs above.
