O.S. P3 Turbo Glow Plug "Ultra Hot"
About this part
This is the O.S. P3 "Ultra Hot" Turbo Glow Plug. Choosing the right glow plug is critical for peak engine performance and there are a number of different factors that will determine which plug you should use. Engine type, air–fuel mix, nitro percentage, and even air temperature are things that must be taken into consideration. What's more, the ideal glow plug choice will change as conditions change. Keeping a range of glow plugs on hand will help you fine–tune glow heat and enjoy maximum performance in all conditions.
Generally, Hot plugs promote better idling and acceleration. If your engine runs rough or accelerates sluggishly, a hotter plug will help. Cold plugs produce more power and may improve performance if your engine runs hot. The downside is rougher idling and more difficulty in tuning.
Some other things to keep in mind are:
- The smaller the engine, the hotter the plug.
- The higher the nitro content, the colder the plug.
- The hotter the day, the colder the plug.

Use these plugs all the time and they seem to work great. They survive engine break-in and will keep going for a few gallons in some instances. As with any plug it only takes a very small impurity to damage the element.
The BEST glow plug on the market right now! It provides exceptional glow performance for all your OS glow plug needs. I’ve had great success and reliability with these plugs, and they’ve become a staple in my racing program. Highly recommended for their consistent quality and effectiveness. Five stars for sure!

Reviewers largely report good performance from this glow plug. Two of three reviews describe reliable use, including surviving engine break-in and lasting several gallons of fuel in some cases. One reviewer notes that a small impurity can damage the element. A third reviewer rates it 3/5, saying it is acceptable overall but that one unit failed after about a week, with no further detail on conditions. Reviews are few, and one is a strongly favourable endorsement.
