Was looking to change plugs in mini I saw people talking about using the brisk QR12LS plugs
But on outmotoring site it says

BRISK Silver Racing QR14LS Stock Heat Range
BRISK Silver Racing QR12LS One Heat Range Colder
BRISK Silver Racing QR10S Two Heat Range Colder
BRISK Silver Racing QR08S Three Heat Range Colder

Anyone using the QR10 or QR08 ?
thanks

 

Here's a good explanation of heat ranges and when to change them. I'm using HR 10 NGK's --- had a bad experience with Brisk and never went back.

If you're interested, here's some NGK numbers for at least the R56, the last digit is HR ---
NGK 91975 R2556G-8
NGK 93253 R2556G-9
NGK 91975 R2556G-10

All are Racing plugs and R56 OEM is HR 7

 

Hi
Thanks for the info and the reply, I was looking for a silver plug, thats why I was asking about the brisk.

 

I see the plugs you listed are copper now that I read up on them. Where do you buy yours from ?
thanks

 

Sourced from Summit. Plugs are considered to be iridium. Check the specs for one of them --- https://www.ngk.com/ngk-4962-r2556b-9-racing-plug
