I believe that is what that is. Mine definetly doesnt have it in it anymore, it takes it forever to heat up unless you start beating on it.

The griffin radiator/transcooler will be in before our next race in a month. Im really hoping that the derale cooler and the radiator will be enough. That should be a good setup if you choose to go that route. The radiator was only $350. 33x19x3 so its not exactly small and allegedly will support 900+ hp

The bottom radiator hose is 1 3/4 so an adapter will be required, and the top vent line works off the cap, so you can just take the spring off the cap and essentially make it work just like the factory setup.
I will post pics when its done.
