If it isnt the UPF64 R what is it? No correct filter for C6 ZL1?
That’s interesting.

So this may be a bigger deal than I thought.

Again, GM’s very own system said use this filter. The dealer had 1 PF64, but 10 of these in stock.

Perhaps they want a higher/ or lower, cracking pressure? He referred to it in the system as “performance” filter. So I went with that.

Add: I will report what’s on the car when I change the oil. Perhaps GM is using these out of the factory now? Maybe others with recent 21’s can report what there’s were.

Damn my curiosity is stoked now.
