From what I was told you had to use GRP plugs something about the taper being different. Was told by the hobby store one of the reason why I buy one

If your going to stick with GRP plugs run a #4 plug. But YOU CAN use a OS P3 or P4 plug with zero issues.

I would stick with the GRP plugs if you could. But if you had to use a OS plug it will work like previously mentioned. It's best that if you do use an OS to keep using OS plugs and not switch to another brand because the taper is a tad bit different between those turbo plugs. I have seen head buttons that deformed a tad and wouldn't seal to either after someone kept switching brands a bunch at the track.

you can also use odonells plugs ....if you use o.s. plugs you had better get a bunch of them as your head will leak fuel around the glow plug if you switch to other plugs ...

Yes, you can use the OS plug in your GRP. Personally, I think the GRP6 plug is way too cold. If your going to use the GRP plug, use the GRP4. This should cure any flame out issues you may have encountered.

If you opt for the OS plug, the P4 or P3 seem to work the best. In the GRP thread there was someone that mic'd out the two brands and found that the very tip of the OS plug was a tiny bit different in the taperor length, but not enough to make any difference in the seal. I switched to the OS plug, based on availability, and price. In a pinch, I was forced to go back to a GRP plug one day, and didnt have any issue with leaking. I went back to the OS plug, and still no issue.

This is just my personal experience with the two brand plugs. 8+ gallons later my GRP is a little tired, and needs a rebuild. I will continue to run the OS plug when it is revived.
