Stock is generally fine, however if your tracking or going through multiple heat cycles on your drives id recommend er12s from brisk. I run them and they havent skipped at beat. Intervals are shorter for changes.
I use brisk standard temperature. Work great
I switched to brisk just because of the high amount of ngk knock offs and they are supposed to last a bit longer and or have less wear than the ngk I'm a step colder rr4ys they have been great.
I recently took my stage 2 43K mile b8.5 s4 apart and did the PCV, water pump, thermostat, new 2 step colder brisk spark plugs gapped to .25. I took the spark plugs out and noticed heavy carbon and the ground electrode was white, even on all plugs . (20 miles on plugs)
You get a better performance if you install a booster plug, DNA air filter and Brisk spark plugs. Great torque from 2000 rpm as a result.
I use a Brisk n17yc.
I just run oem plugs gapped to . 024 as recommended by eqt who I'm tuned by. No knock, I had brisks and Ruths before, my car didn't really like brisks and Ruths just made it misfire closer to the 5k change out.
Get a Brisk spark plug. Worked for me
Been using the cheaper Brisk brand and never had an issue for 20k miles.
Heat Exchanger, also Brisk racing spark plugs I gapped mine to 0.026”.
