I have an oil cooler on my A15. I think anything that keeps the oil cool is good for the engine. I probably have one of the more complicated systems other than using a dry sump.

I have a remote oil filter plate with a checkvalve so we don't loose prime ( it also keeps the oil flowing to the engine and not draining back so it helps maintain oil pressure, then it goes up to the oil filter mounted on the strut tower, then crosses over the engine to the oil thermostat which sends 5-95% of the oil through the cooler before dumping it back down to the oil pump.

if you have clearance issues get a remote oil filter plate and then you can out your oil filter somewhere easy to get at.
