Spark plug advice roush phase 2 727HP

[boostmark]

Looking to change plugs on my 2015 pp roush. Looks like the stock plugs were used and I have no clue as to what these should be gaped at or what a good upgrade would be.
Seems like tuners prefer silver plugs to get rid of heat. Any advice would be great. Mark

Well I just got these changed out yesterday and its back to full power. The stock plugs were about 10 thousandths out as most were gaped at .038. What a difference. Thanks

Good to hear you got it worked out.

Just remember. You have to change the plugs more often on a boosted car. I change mine every 5000 miles. (About once a year).That might be a little anal. But it’s also cheap piece of mind.

I just changed mine at 20k. I can definitely feel a little difference so I'll probably stick to every 15k moving forward.

ngk 6510 gapped .028 .. anti seize because the heat will effect that change in plug tread pretty quick, i have a blown 700+ hp 2018 and i think this plug is amazing. industry best IMO

Anyone using the brisks? After seeing everyone agreeing on the ngk I was thinking of switching.

I am running Brisks with my whipple stage 2. I was originally running NGK but my tuner recommended that I switch to the Brisks. I haven’t had issues with either plugs though.
