My supply of P7TC (picco turbo cold) was getting low and these appear to be in short supply right now (in the US). I believe Novarossi and Picco plugs are not interchangeable, but I think O'Donnell plugs were(but are also in short supply).

So, does anyone have acceptable alternatives to the Picco P7TC plug? I have seen comments that REDS and OS were compatible but no idea which are a best match.

I searched for a cross-application chart (like springs!) but didn't find any. Does anyone know of such a chart?

Thanks for any help.

OS RP7s

thanks, I will try that. I can't remember who told me they thought OS plugs were a good choice in general. Are they universal fitment like Odonnell?
