If you are tracking your 86, then there is a very good chance you'll need to add some additional cooling to your vehicle regardless of the region you are in. With our Project BRZ, we found out real quick how hot the 86 engine can run.
Mishimoto is one of those companies that has been in the industry forever. Their all aluminum radiator includes TIG welded end tanks, 100% brazed aluminum core, a larger cooling capacity than stock and their Lifetime Warranty. Again, if you're out at the track, installing an aluminum radiator should be high up on your "upgrades list".
