Spark plug / coil replacement

[Sikh_Supra]

Hey everyone, I was searching the forums but there seems to be lots of different answers. Which would be the correct spark plugs for our supra!

NGK 97506
Or
NGK94201

as for coil packs does anyone know the BMW part number? Dealership is saying 2-3week wait for coils to come in. Maybe bmw dealer has in stock.

Speed Industry recommends the 94201, but I came across a conversation on social media, talking about best plugs. And apparently the champions (stock) are 1 step colder than the ngk 94201. Maybe somebody can verify that for me/us.

I want to say I saw the same info on the B58 FB page. Something about the length of the plugs is different and the champions being the cooler plugs. I've also heard some ppl using BMW i8 plugs. Have not confirmed what the difference is, but i am curious.
