Warm engine is good for testing the cylinder health , cold testing is best when checking the “oil pressure” so you can record the “cold value” and “hot value” as the oil gets thinner and circulated.
Yes fake NGKS exist but sadly i’ve tried other brands , and NGK wins every time especially with their own NGK caps. Just that the “IX” in particular is more overhyped and quite an annoying plug.
I’ve got the same LASER plugs in one of my bikes for 2 years and has not missed a beat, LASER is also OEM to some Suzuki bikes. So go to a Suzuki dealer and ask for a CR8E LASER plug. Suzuki using LASER plugs is enough confidence for me to keep using it. It’s usually NGK’s flagship plug for bikes (also most expensive for good reason)
Here is more info on NGK’s official site in regards to spotting fake plugs:

if not , go to a BMW dealer and ask for a BOSCH plug to replace your CR8E , as BOSCH is typically an OEM plug to some BMW bikes & BMW cars
