Brisk makes some for about 80 dlls for a set of 8. Try a search, I posted some pics some time ago. Most people here like the NGK TR55s so you are probably better off sticking to those.

i switched from OEM plats to ngk tr55's and my gas mileage went to crap. Prob cause its a colder plug (heh, or b/c of the headers) but just wanted to give a caveat.

NGK Tr55's are the stock heat range. It's the Tr6's that are one step colder.

Nothing wrong with stock plugs on mild motors.
