This cooler made a huge difference in oil temps during road racing. I wouldn't even road race with out one!!! Cooler is a tru-cool 24 pass, lines are -10an stainless braided and the sandwich adapter is a Mocal unit with a 180degree oil thermostat so you don't keep the oil too cool. Cooler is attached to radiator/condenser by running tip ties through all 3(between fins). I chose to go this route over rubber lines because I didn't want to risk my billy-bad-ass motor over a freakin $5 rubber line. This way was more costly, but I know its not gonna rupture.. and besides, it looks pimp!
