August 1, 201313 yr ok my car mods are cat back system cone filter 14psi boost jets and chip for fueling stock plugs. should the plugs be chaanged at this point of tuning for diffrent heat range and will the gaping of the plug need to be changed?
August 2, 201313 yr Here we go again.... :) so many different opinions on this... not that I can say that I noticed anything wrong with iridium but a 6 or 7 range plug should do fine (pre-gaped). I prefer platinum (as in the manufactures recommendations) again pre-gaped. you could use copper but they will wear out much faster (you might need to work out a gap for them).
