The intercoolers fit nice, install nice, and work great. It is our preferred bolt-in intercooler system for the OBS trucks. We've got them available and ready to ship if you're interested...shoot us a pm for pricing.
I would agree Hypermax has always made nice stuff. I would probably consider some other places for injectors first but there is no reason at all not to consider an intercooler from them. Banks also has a nice OBS intercooler kit but it is a little pricey.
