Medium-reach plugs include: the hot R2 sport plug and R2 Plus designed for vehicles with a PRO-18 engine; R3 for stable idling and smooth acceleration in aircraft engines; cold R4 for high-nitro fuels and cold R5 for use with fuels with up to 25% nitro content. Also available: RF glow plug for 4-stroke engines.
