Has anyone tried using the larger type 4 oil cooler? Looks identical except it has 2 more cores. I was thinking of modifying the doghouse to clear the larger cooler to increase cooling. Looks like all I need is longer studs and to widen the outside part of the doghouse to clear. It matches up exactly except for the part that sticks outside of the box already on the type 1 cooler. So I should only have to modify the small duct on the front of the doghouse.
