Hello everyone. I have a question. My TL just hit the 100k mark.....so I decided to replace the spark plugs. I brought the plugs from Rock Auto.....it suggested that the NGK iridium were OE for the 3.7. When I took the old plugs out they were denso iridium plugs. So I thought that was kinda weird seeing denso plugs in there when it was suggested NGK. Is a difference between the two plugs? Will there be any problems with the NGKs?
