Is the black tube on the backside of the oil cooler = for cabin heat?=A0 How well does that work?=A0

Mark, I have two of the DB-30416, single-pass cool= ers =85 no measureable pressure drop with 2 in series =85 I=92m seeing 80 p= si max with the 13B.

What do= you mean =93 . =85 no measurable pressure drop=94?=A0 Are you measuring pr= essure before and after the 2 coolers?
