Has anyone put a Banks Techni-cooler on their 6.7? Did it make a difference? Is it worth 1200.00?

I've sold a few, all positive feedback so far. Though at your current power level I don't think you need one. I would put that money towards tranny or fuel system upgrades.

I was going to probably go with an Air Dog next.
