Turbo Plug?
Which turbo plug would be the best to put in a Promo Grp .21?
I've been using a P3 OS plug but I've been burning through them like it's nothing
I was wondering what other plug would be best to get
Any suggestions?

The P3 is too hot for a GRP.
Use a P4 or O'Donnell 77T.

GRP's own 5 or 6 plugs work well; as do Novarossi #5 or 6's.
