so what about these sandwich adaptors that direct all the oil through the cooler? when I converted my 2+2 I took the tt oil filter tree and capped off the ports for the cooler supply and return and ran it thru a sandwich adaptor. after 20,000 miles I have had no problems. oil stays about 180 degree normally unless m driving hard and my oil pressure is jut a tad low once i'm up to operating temp
