hey all, I've recently installed a caldina 3s-gte into my mr2 and want to replace the plugs. I did a search and it seems that most posts have been to go with either Denso or NGK but not into specific's as to which plugs and our dealers here don't know what to recommend (short of pulling one out).
Can anyone confirm that the OEM plugs were either Denso Iridium Spark plug, (PK20R8) or NGK Laser Platinum BKR6ep-8? (I got the part #'s from toyodiy.com
Also I picked up a set of NGK G-Power BKR6EGP plugs (which I believe are one level down from the laser platinum), any thoughts?
Finally, I know for the mr2's at higher than stock boost (anything over 14psi) the popular plugs are the BKR7E's, is there any similar wisdom with using those plugs with the caldina motor?
thanks!!
