OEM oil cooler removal with aftermarket?

Jordo!

Well, right.

If you aren't tracking the car or routinely seeing excessively high temps in whatever constitutes your "normal" driving, the extra cooling is overkill. But I wouldn't say "everyone over heats with it, period".

While there are quite a number of owners who have seen very high temps off the track, there are also quite few folks who are under cooling, running consistent temps around 150* -- that's too cold for heavy load.

Really, what would be nice is something with a thermostatic plate that was water cooled for faster warm up and kept temps under sustained load pretty much dead nuts on 200* (air cooled, methinks, being more track-friendly). But anything under 240* F is fine, although over 200* I believe the ECU will pull a bit of timing.

For an extra 10 - 15* cooling, I found the ARC cool fins actually work quite well -- basically just adding metal fins to the under side of the oil pan. I see very fast cool down between runs on the dyno too.

Behold:



I also have two stuck on my diff cover
