I just installed a set of Brisk racing plugs and gapped them to .025 and my idle is smoother, a lot smoother in full boost. If you are tuned the magic gap is .025 and these Brisk plugs are damn nice.

Mine is completely stock and I have super rough idle? Is it safe to do the SP-534 to .030 with out a tune? if so I am ordering tonight.

I would go .030-.033 without a tune. Anyone having rough idle with an EB needs to check this. It takes like 10 minutes to check all 6.

What year is it? I think the late 2012's and '13's already have them.

If not the above, you can put them in with no issues.

The stock gap is .34 correct ?? I heard that .30 gap is the best for these motors ... I haven't done mine yet as I'm still dealing with ford on this. Trying to get them to admit that they are wrong and need to change them.

Stock gap have been all over the place, but that could also be user error. The 534's seem to be consistent around .030, which mine were.

Mine is a 2011. I also have found these part numbers for the autolite's and the NGK's. NGK ltr6ix-11 and Autolite xp-5364. Just want to find what is going to perform the best with out the rough idle.

I am wanting the SCT Live wire but haven't done much research on the best tunes for my application.

TwinSix

Is your truck stock?? Mine is stock and I absolutely love the SCT Live Wire and plaid Franchie is running a group buy special on them ;-) ... Then later on you have a ton of options on who to get your custom tune from ....

BluefireTT

Yes it is stock and the only upgrade I have done is 2.5 level and 295-70r18 Nitto Trail Grapplers on.

Awesome ... I'm thinking about putting a leveling kit on mine as my 275/65/r20s rub a little when making some turns ... What kit did you use ?? And are you happy with it ?? Did you install your self ?? I did my Chevy my self and it was a pain lol ... I've seen some kits that say "easy installation" but didn't look to hard at any yet...
