The NGK plugs I got were the IFR5T11 which I am guessing is the IFR5A11 but a different number since it says they are the OEM replacement.
The only problem is the NGK plug is gapped at .032 sooooo I am guessing I need to widen the gap on these puppies. Some of the guys at Advanced said I shouldnt gap them since they are Iridium plugs, but the service manual says new plugs should be .039 to .043 in.
So in theory I should widen this gap?? Also why does on
www.sparkplugs.com show that the OE gap is .032 but when you highlight the product to the right of it is a picture of the plug and the specs on it and then at the bottom of the specs it says .044" (1.1mm) Gap
