Eco spark plug gap

V-8 Sounds Great
Just noticed you said had Gotts mod on your ecoboost. Have you noticed anything with it good or bad? I was thinking of doing this as I am not willing to spend bookoo bucks on an intake, but I'm looking for better flow. Thanks.

So far the differences i can tell right off hand are:
The gotts mod will keep the intake temps closer to outside temp but will heat soak faster after turning the engine off. It also seems to give me more audible turbo whistle but i will have to put the cai back on to see if there was a difference.
This comparison was with the cai with snorkel on and the stock box with snorkel off

NGK LTR6IX-11 is the plug that should be used. This is already one step colder (as spec'd by Ford) than the ideal plug heat range to prevent fouling. The LTR7IX-11 (colder plugs) will still work, just be aware that unless you run your truck hard or have serious modifications done you will be more likely to have carbon buildup on the plugs and thus a return of the original symptoms.
If your truck has a lot of condensation happening in the intake, stay away from colder plugs!

Well I took a 125 mile trip on hilly roads going to our camp site for the weekend, and having my plugs gapped to the correct .035 had zero effect on the way it ran, the up hill shudder, or fuel economy.

Just gapped mine. All were between .030 and .034. Set em all at .034. Fairly easy job.
Interesting thing, the driver side bank plugs were awfully black and carboned up where as the passenger side plugs looked fairly good. The driver side plugs were also all at .030 or smaller factory and the passenger side were all at .034.
Idles the same. Won't be driving it until this evening when I go to the bar.

I didn't expect it too. It's just some more rumor crap that gets started on the internet. So how many have needlessly changes their plugs or gaps with no noticeable results? most of them.
