The plan is to install a Mishimoto sandwich adapter at the OEM oil filter location and tap a 1/4" supply line from the adapter to feed the Frantz filter. The filtered oil will then return through the oil fill cap.

I currently have a clean-side oil separator from Tracy Lewis, but I’ll need to repurpose that separator for the oil return line from the Frantz filter. Because of that, I’ll be adding another catch can — a Mann & Hummel ProVent 100 v2 — to handle the crankcase ventilation between the valve covers and the existing air intake nipple.

It should be an interesting project. Once everything is complete and I have some results, I’ll post a full write-up in the DIY section.
WIX filters are great! I used those until I became a Dealer for Amsoil and started stocking an abundance of ZLE Filters.

I would recommend against using the Mishimoto Sandwich filter adapter for an oil cooler. I will say I have ZERO experience with the V6 platform, but if its like the LT4, the sandwich adaptor can lead to bypass issues at higher RPM. I have several customers who bought that system only to have massive cooling issues when at the track. Around town driving with low RPM sustained use, it works fine, but in a track environment, it miserably fails. Also understand their heat exchanger was designed to flow Glycol based coolants, not oil... so the flow rates are also an issue and have been known to cause starvation at high RPM again in the LT4s leading to a bypass.
