So I decided to build my own bypass system for my 13 Ram with the 6.7 cummins. I have pretty much everything to build it already but I have to order a Filter base. I was planning on using the Baldwin OB1308 but just have a question about it. The OB1308 has it restrictor built into it that the oil goes through before entering the filter. Is the restrictor in the OB1308 enough or does another have to be added? Also if anyone knows of a better filter base please let me know. Thanks in advance.
