What should I expect to pay for these plugs?? Can I get them at the local auto parts store, or is online easier/cheaper?

I paid like $3.30 per plug at PepBoys, they had to special order them for me took about 2-3 days to get them. I have installed all four plugs and all seems good (knock on wood). I've also switched to Mobil1 5W30, and will be probably getting the valve, all percautions, better safe then sorry I suppose. Right now I boost spike to about 11psi when it's hot, and when it's cold it spikes a little higher closer to 12psi. I have never once hit fuel cut, even when it's gotten as cold as 50f. I am really enjoying my Speed and can't wait to pick up a nice intake/exhaust and maybe even a FMIC.

As for the PCV: ask your dealership for the 323 GTX`s....it fits just fine.

would a external oil catch canister work?
