Best Spark Plug for stock motor with Roush kit/82mm pulley

[SB302]

I'm about to change plugs and was looking for suggestions for car that has a Roush supercharger kit w/ 82mm pulley making 10lb of boost.

2011 5.0 w/Roush kit 82mm

Suggested plug?

Discussed many times.

NGK 6510 and some go with Brisk brand, but NGK is trusted and proven.

I don't know why JPC pushes the non projected brisk plugs, for a car that is only drag raced, yes non projected plugs maybe a good choice, but not for daily driven cars. JPC put non projected plugs in my car and they just fouled, so will never put non projected tip plugs in my car again

I like NGK 6510's the best, but Brisk are good too, but not the RR14S

if you want to go Brisk get the projected tip RR14YS

Im running VMP's stage 3 kit with a 79 mm pulley and VMP recommended the brisk RR14YSwhich is a one step colder plug. That's what I put in. I think any one step colder plug is what they recommend for supercharged setup.
