The ACDelco GM UPF63R Engine Oil Filter is designed to provide superior filtration and long-lasting protection for your engine. It effectively removes contaminants from the oil, ensuring smooth engine operation and optimal performance.
AC Delco's best filter when you see the U & the R in the filter name, heavier wall construction and slightly more filtering capacity. I only install these on my Supercharged Z06 and CT6-V with the Twin Turbo Blackwing engine
