OS Engines P3 Turbo Glow Plug – Ultra Hot
Get the most out of your .21 nitro off-road engine with the genuine OS Engines P3 Turbo Ultra Hot Glow Plug (SKU: OSM71641300). Choosing the right glow plug is one of the most important tuning decisions you can make — it directly affects idle quality, throttle response, and overall engine performance.
Why Plug Heat Range Matters
Engine type, air-fuel mix, nitro percentage, and ambient temperature all influence which plug heat range is ideal. Conditions change between race days, so keeping a selection of plugs on hand lets you fine-tune for maximum performance every time you hit the track.
- Hot plugs (like this P3 Ultra Hot) promote smoother idling and better low-end acceleration — ideal if your engine runs rough or feels sluggish off the line
- Cold plugs produce more top-end power but can make tuning harder and idling rougher
Key Features
- Genuine OS Engines OEM glow plug
- Ultra Hot heat rating — optimised for .21 off-road nitro engines
- Turbo design for consistent ignition and combustion
- Improves idle stability and throttle response
