Hello all I was curious if anyone has ever tried non-projected (stock are projected) like most race plugs?? So that the tip is at the level of thread end. Why I ask is Denso has cooler plugs than "9" NGK which is 31 in denso heat range, but it is flush or non-projected tip. Their is some evidence to support cooler plugs help with pinging and non-projected to help with pinging also. Thanks for any first hand accounts.
