Where is the best package price to both purchase and P/P stage 1 that will still pass smog in Cali. My number 3 plugg blew through my stock heads and I need to replace them and might as well take care of the stage 1 at the same time.
I have a set that im taking off my car. They probally only have about 2000 miles on them since they were p/p. They also have over sized valves in them. I'll let them go for $800 + s/h.
