Spearco core.In for final impressions of all 3.
It would be worth asking your builder of the custom IC, what core type and manufacturer it is. That is the important factor. Greddy/Spearco/Bell are the age-old bees knees. If he used one of those, I'm surprised. But also not too much at China cores catching up.
Speaking of logs. Let's poke the bear and see who has empirical data where the doing away with the OEM quick disconnects on the inlet/outlet is a good idea.
Funny how VRSF's F2x intercoolers have the same "small flow restriction" CNC'd quick disconnects on them and no rubbish hose kit (they are all rubbish, Wagner, VRSF etc).
