Can anyone tell me the diff between these three plugs. (see pic)
I was going to order some and noticed the same plug W/three diff titles.
From what I understand they are all conical so what is STD.

1. STD
2. Conical
3. Plus

I know GRP makes a weird plug where the element actually sticks out of the plug. Maybe that is the plus version. Not sure.

No the pics are correct I copied them right from the website. (see link below)
A friend says the plugs are all conical but the plus version is for winter type racing weather rain/snow.
After talking to him I went back to the sight and noticed the STD version which then brought up more questions thats why I asked here.
I know it's probably not a big deal just like to be informed and don't want the wrong thing.

As replied in the Picco topic:

All 3 plugs in your attached picture are the same, so there is no difference there, BUT:
If you check the GRP site and look at there product information, you can read about the difference....

I have a question to, are this number the engine temperature you need or the outside temperature {weather}??
4 hot
5 medium
6 cold
7 very cold


Because in florida most peoples use #6 and #7 hot temperature!!!

the temp you run has alot to do with engine size, nitro % in the fuel, and temperature outside.


it can be 80 out but if you run 30% nitro in a .21 you might want to run a slightly colder plug.

As you can see, the pic is wrong. That first one should be a standard plug, not a turbo or conical. Just because it's on the web doesn't mean it's right. Hell, I post wrong stuff all the time

Yep you were right not having bought these plugs before it just through me off.
My old nitro car used standard plugs so they were pretty easy #8 long.
Thanks for replying.

Anybody else tried out the 'Plus' plugs? I ordered a set, but that extra exposed filament makes the plug just a tad longer than the regular turbo plug. Just a slight worry about the piston hitting that. I doubt that it would (can't see GRP getting a patent on a plug that will destroy your motor), and I ran one last weekend with no problem (at least once I got the carb straightened out, which was another issue entirely).

The element would have to stick out more than 8 or 9 mm to hit the piston. Remember the plug sits way up at the top of a domed combustion chamber. It's no where near the piston.
