I have a new idm .12 3port and breakin is finished and running well. On inspection of the plug the coils are shiny but are distorted a little. not in the too high compression/too hot pushed in way but kinda pulling out of the plug body a little bit. I had read on another thread this could be from a pipe that is moving too much air? I am using 7mm zac pipe. could this be my problem and if so can i put a 5.2 mm restrictor on the stinger or will that cause more problems?
Thanks for your help.
Could also be because of header beeing to short. Also i'd reduce stinger first to 6mm and then to 5.2mm and compare.
