Im Trying to find out if 2j spark plugs will work in a 7m. the plug at hand is a Denso Iridium no. SK20R11. Toyota PN-90080 91180. They look almost identical to 7m plugs, but im wondering if there may be some internal difference between the plugs or any reason they wouldnt work. If anyone can touch on this subject, it would be greatly appreciated. Thanks -Sean-
