I can get them from a friend for real cheep and i was wondering if it is worth it to put them in my car (in Sig). It has 28,000 miles on it. What is the advantage over stock plugs?

 

I've used the single electrode Bosch plus for a good 13 years and have nothing but praise for them. I think Bosch is certainly a much more reputable manufacturer than splitfire. Sorry Rob, but I have to disagree with you: The Bosch series of plugs are a good product and I'll be trusting my new Minirammed stroker motor to them. In all the time I've used them, I've never had a misfire that was due to the plugs. I actually have a set that ran 50,000 miles in the Trans am, and they could probably go another 50,000 if I wanted to reinstall them.

have them and love them!!! but i gotta ditch them now, only because of nitrous, but thats the only reason!!

 

I run AC Delcos in my cars and I've tried platnums before, AC delcos work better in my applications.
