Those look nice but I don't plan on doing extended OCI so I think it would be a waste for me.I went with the PPE on my last change. It was $34 shipped so I don’t know if it’s worth it but it is actually a filter made for the engine, instead of a filter used on every other gasoline car gm makes. I will be sending a sample to. Blackstone within the next 2 weeks so I’ll see how it’s working.
I just received my WIX filter, after a 3.5 month wait from Summit Racing. Just ordered it in the blind knowing it would be a while. Will use it this spring on the next change...ACDelco UPF66R rock auto has them back in stock, the WIX filter has a smaller micron rating.
