[QUOTE="greengt88, post: 9264253, member: 95710"] i have very similar mods to you, i had steeda install NGK TR6 #4177's with a .035 gap, idled a little weird, had like a miss typr sound, car ran great though, then i installed my SCT X3 with their 93oct. tune and it got worse, then had pulley, belt and aux. idler installed with a tune from Amazon Racing and the little miss completely went away. Alot of people have experienced the little miss from these plugs, but i don't know what tune they were running, so i'd say it's not the plugs but the tune. I would certainly recommend these plugs to anyone. Steeda agreed also that it had to have been from the canned tune in the SCT. These are a heat range colder than stock and explains why they felt that way w/out the SCT tune. Not burning all the gas. So get them and a good tune, should be excellent. Others may chime in about how the iridiums cured this and vice/versa, but they are pretty much tried and true. All the vendors sell them, they are really cheap as well. [/QUOTE]
