I only run these plugs when I decide to go from my 25% nitro to 30% I only run those two percentages I run the OS brand glow plugs are deffently worth the added cost long life easy to tune I keep an array of OS#7 OS#8 an OS#10 plugs an with those 3 temps I'm able to tune for bout any weather track or nitro combo I chose to run. I may run mostly LRP mills mainly cost to performance issue on why but these plugs have been the best I've used as far as ease of tuning there longevity an ease of reading the plug to know how the engines acting and liking the tune I have on it. I know it's a preference an maybe some will agree while others will say that they prefer a cheaper plug that'll do the same but IMHO for something that's so vital to your engine why be cheap they last for a long time not only that I've yet to burn one completely out when I change these plugs out its almost always cause I've put close to a half gallon thru my engine an I change it just to be safe an keep the performance up or cause I'm going to 30% from my usual 25% bash around an at that time I'll go from my normal go to plug OS8 to a OS10 unless I'm breaking in an engine an wanna keep some heat to the motor an keep it from stalling I'll go with a OS7 only other time I use that is if it's 10 degrees outside an I know the engine is barely going to crack over the 220 range I'll keep the OS7 in it. Either way I feel these are by far the best standard plugs you can getRead full review

I bought these to try in my .15 to .45 size engines used in freeflight, and some in control line speed type engines. So far they seem to last pretty well. They seem to last as well or better than the KB 1S and 1L I have used.
