spark plug help
 

After reading a spark plug thread here, I decided to move up my scheduled plug change. Has anyone ever heard of Pulstar plugs? If not what plugs do you guys recommend for 2011 ecoboost. https://www.pulstar.com/thumbnail.ph...g&size=flipper

Motorcraft SP-534's.

what he said ^^

ford spent a TON of money figuring out the plugs. they have the heat and timing down. do your engine a favor, run 534's, amsoil signature series (low noak oil), and a catch can. your engine will run amazing. hope this helps.

I just ordered as set online. How should I gap them? My 2011 is stock.

.030-.032"

Are they supposed to be gapped different if they are tuned?

Some guys with high octane tunes are running .028" They come gapped at .032".

39.00 dollars for all six with free shipping. I hope that was a good deal, it seems like it is.
