Oh I agree the sandwich adapter is much cheaper and better than a bunch of brass fittings hanging under the car. The only problem that I see with the sandwich adapter is that you have to use a shorter oil filter which to me means less filtering capacity and I didn't like that idea.
I run the sandwhich adaptor between the remote fitting and the engine and run a longer than stock oil filter at the fender
My glowshift sandwhich adaptor has 4 ports, im going to be using one for oil pressure, one for temp and one for turbo feed.
