OK. Here it is. I'm trying to decide between Denso IT-20's and IT-22's..............
The Denso cross reference chart says that NGK TR-5's equal IT-20's. I am currently using TR-6's (which are one step colder than the TR-5's according to the NGK site). The Denso chart doesn't have TR-6's listed. SO..........does that mean that the TR-6's would correspond with the IT-22's??? Since the TR-6's are one step colder than the TR-5's, could it be assumed that the correct Denso plug would be the IT-22???
Thanks for the input.
