Spark plug advice roush phase 2 727HP

[ForYourOwnGood]

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

Putting anti-seize in aluminum heads like that is a real good recipe for pulling the threads right out. There is a reason your manual tells you to change the plugs with the engine barely warm and do not use anti seize, it acts as a friction modifier and you end up torquing them more than you intend to. People get away with it sometimes but I've dealt with the fallout more than once, no thanks.

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.

Thanks for the reply. I had the brisks recommended and have been happy with them. Was just a bit surprised when no one mentioned them above.

I know this is an older thread, but what plugs does the Phase 2 come with stock? My car stutters a little while cruising at a consistent speed. I drives perfect with anything over 10% throttle. I'm wondering if it could be the plugs.

Gap them at what your tuner recommends. .022 here with Twin Turbos

I ran NGK 6510’s gapped at .028 on my 17 Roush Phase 2.

Depending on the applications we build we range in the sparkplug gap also

Boosted applications we typically run a 6510 +LTR7IX-11 at .028" to .026" Depending on boost level

However we do gap some setups as far down as .022" Depending (this is typically Turbo setups)

We have a Stage 1+ build we are doing (our inhouse package) Using a Roush Stage 2 gen 3 unit and we will be gapping them at .028"
