Spark plug recommendations please: 2015 GT

[Rubybarchetta]

Hello,
I have a 2015 GT with an R&D Thermo cat-back exhaust and a CAI. (NO Tune)
I am having a difficult time determining which Spark Plugs to use.
Should I just use stock eqiv NGK LTR6AI13 with a .050 gap ?

Thanks for your help

Use the stock plugs. I like .040 gap but that is just my OCD.

The OEM ones, they work fine.

Just had mine replaced along with a #8 coil malfunction. Then an extended warranty IMRC problem fixed with new intake manifold. Car runs great.
