Thread: Question about plugs

i want to eventually put a 3.4 inch pulley on my car, but not until i get some money. I know i need to get colder plugs so i plan to get autolite 104's. i need new spark plugs soon so i figured i would just get these ones now. Is it ok to run on these plugs with the stock pulley?

its okay to run them with a stock pulley, but your mileage might go down because of the colder plug. you always want to try and run the hottest plug you can without knocking.

cool man, thanks. didnt want to have to buy another set of plugs when i decide to do the pulley.

buy another set? autolites are cheap as hell. you can get a whole set for under $5 probably.

wow really? didnt know that. ill probably just buy the 104's anyway. are there any other plugs you would reccomen also, or are the autolites fine?

autolites are going to be the cheapest copper performance plug youll get as far as i know. i havent bought anything else. i run 104s on my setup as is, but i may end up going to 103s if i drop a few more pullies.
