You can purchase the ZHP knob on many websites, as of August 2021 it was the cheapest on ECS Tuning. Part# 25 11 7 896 886
The OEM non-ZHP knob can also be purchased there. If your knob is as worn as mine, this is a very worthy upgrade for under $100 and is easy to do, requiring no tools but just some strength :)
I'm very satisfied with it! Thanks for watching!
