Is the OS P3 a good glow plug for the GRP .21?
Anyone?
I would say it should work fine, I used some merlin plugs and they werent bad, No reason to spend 12-15 dollars on a plug made by grp, They are a great quality, but it will burn up just as fast as the rest of them, depends on what climate you are in as well, different plugs for different temps.
