I would double-check it again after a couple more drives / days....just to make sure you got all the air. I actually had to do mine twice.

Next, A lot of guys are also running aftermarket radiator like Full-Blown or Koyo......They work great to keep the temps down.

There are also a couple of aftermarket oil-cooling systems that you can get if you want to take it further. A number of the guys who regularly track their cars use them.
