i have a 02 ep3 thats boosted, what plugs would you guys reccommend, or what are you guys using?

 

Depending on how aggressive your motor is, go colder in the heat range of the plug. I personally like NGK's, but there are lot's of other good brands as well. For a bolt on kit stay stock or one step colder, for an aggressive setup, go one to two steps colder. Be aware however, that colder is not always more conducive to more power, just better suited for the application.

 

ok thanks, i heard i should just go with the stock rsx type s plugs becuase they are one step colder than stock ep3 plugs
