Hi! Wondering what plugs you use for your turbo boosted S2K. What kind of gap? Thanks in advance for your response..

 

Use 1 step colder plugs most use on here: BKR8EIX # 2668

Use .20 - .24 gap & no higher. I say target .20, a lower gap as there is less chance of spark blow-out. The more you experience spark blow-out (misfire) the higher the chance of you frying your nice coils.

Research might show multiple threads saying larger sparkplug gap results in more power, better combustion and of course "more power." From personal research and from chatting with other tuners, it's a few HP difference if that.

 

Gap it down till no blow out..... that simple.

 

Thanks. That is what I am using. I have them gapped at 30 so I will lower them. Minor misfires now so I will pull and regap. Thanks.

 

Yeah that's pretty wide. For typical pump gas and moderate 10-15psi around 25 I've found to be good starting point. Lower some from there if you need to.

 

Thanks. I am running 9-10# for the street. Ordered new plugs. Will try the gap at 25 and go from there.
