Default VAP tune and Plug Gap on V6S

I have a 2016 V6S AWD and getting the VAP pulley/ECU tune, Mina Gallery Intake, replacing the resonator with an X-pipe done. I'm also changing out the spark plugs..... what should the gap be?

Thanks in advance.

AFAIK the stock V6S plugs are already "cold" and can easily handle the extra power of the VAP pulley and tune and Mina intake (I have the same) without going to a colder plug, which in turn should mean that the stock gap is good to go. Of course I could be wrong and someone with more knowledge can correct my ignorance!
I bought six new plugs about three years ago but have yet to fit them, I am still running the original plugs at nearly seven years old and 42,xxx miles, and the engine is still running as strong as ever with zero problems.
I have one of the new stock plugs in my hot little hand as I type, JLR part # C2Z28434 stock # 93476 NGK SILZKAR7E8S.

Those are the same plugs that I have. I had them replaced as part of my six-year service at about 44K miles, and had the technician number them and save them for me. They're all uniform and don't look bad, but do have what I think are deposits from fuel additives. There's some slight erosion of the center electrode but I'd call them normal and given that they're a PITA to change am on the fence about switching to a 30K mile service interval. I would not go 60K, but most people would probably not notice. I probably wouldn't notice either, but I've looked at these with a magnifying glass and through the lens of 1970s era ignition systems experience. Yeah, probably not the best point of view for modern systems. Not as touchy a subject as oil change intervals though.

I replaced mine last week. It wasn't too bad of a job. I followed DC's DIY posted on this forum. They are gapped from the factory, but I verified 0.9-1.0mm. I agree with the part number OzXFR posted.

Awesome, thanks. That's the set of plugs I got as well.

Id ask your tuner to be sure.
Theres a video on youtube with someone changing his. Gapped them significantly smaller than what’s posted above
