if i use nosram plug, everything's fine but if i use idm plug, the problem came back!
it's not that i cant use nosram plugs but they dont lasts. just after a few tanks, the plug wire would become distorted and dead. (it's not lean at all as smoke is visible and temp is about 110-120degC).
however, if i use idm plug, the plug wire would be ok and the plug could last for a few race days...
what's the issue here? am i stuck with a plug that i've to replace every few tanks?
p.s. anyone knows whether idm#6 is similar to nosram #6 or #7?
