Review on 🔎 ACDelco UPF52 Ultraguard Specialty Engine Oil Filter by Zachary Spaulding

As a side note, if you have a 3800 Series II engine and enough clearance, this filter will actually perform better than the stock filter. It is designed for truck engines, has good flow capacity and contains more filter media. It also serves as an additional oil cooler, keeping a little more oil further from the engine. If you use the latest generation Riviera, you have enough space for it. Just make sure you use the full 5 liters instead of the 4.8 normally required to make up for the extra filter length.
