spark plug choice and gap for bolt on, tuned EB's

NGK 6510 @ .028
is that the correct choice for tune, CAI, DP, exhaust, FMIC?

:help:

has your car been on a dyno yet with the mods listed?

No, working on an e tune with FFTEC. I'll get it dynod when its finished up.

I'm using the ITV22 Denso plugs at 0.028. They've been excellent so far.

Silly question since I've only messed with big n/a cars, but why do we need to change the plugs already?

I didn't change mine with just a tune and they were fine. I just changed mine after some bolt on's based on someone's recommendation from their previous experiences with ecoboost engines. I went one step colder with the ngk 6510s at 0.028 and have had no issues.

hey guys, thanks for the info on your plug & gap choice

How can I re gap the plugs. I rec'd my NKGs yesterday and they are all pre gapped to like .032

I personally use this tool
It's a snap-on

I know the guy that owns NW, he's a great dude. Doesn't deal in FORD or stangs but he has these tools and I bought mine there.

Since the gap needs to be narrowed, you can lightly tap it against a book, table, etc., if you don't want to buy a tool. I have a gapping tool from Advance Auto that I use now, but it's fine to lightly tap them against a harder surface to narrow the gap. Just take it slow and easy so as not to narrow it too much.

Thanks for that tip Juban, I tapped them down to .028.... How bad is the install?

It took me about 30 minutes but I was just kind of piddling around. It's super easy and would take about 15 minutes if you didn't waste time.
