i have my plugs gapped at .35 right now these plugs went in when i did my header install and since then it seems like my car dosent run as good as she used to, (i dont have any idea what they were gapped at before) so do you think i should re gap them to .40 or .45 any ideas on what would be better with my mods?

 

I have the same coil you do and I run the plugs at .045". But I don't think the situation you mentioned has anything to do with the plugs. I'd look for an exhaust leak, something that would throw the O2 sensor off...

Maybe burned plug wires?

 

im gonna change them anyways and regap them....it cant hurt, and ill look for exhaust leaks while im at it thanks for the reply
