Is that how much mark up is on their parts? If so that's horrible. I understand making a few bucks, but jezus $600+ mark up is outta hand.
It's not markup, check other companies prices on intercoolers, the company wants to remove it from last years accounting books...
I paid around 400.00 for mine on one of these sales (LBZ). If it is anything like the one I received the box is a little dirty from sitting and being slid around, the intercooler is in perfect condition. I have been checking for one of these sales for a radiator. See the video for install, reuses all the stock fittings with a minor adjustment at the AC condenser bracket and that is in Mishimoto's video.
Going to replace the fan clutch and that one little piece of hose behind the fan and a few other radiator/heater/turbo coolant lines while I have the truck apart. I did purchase new mounting rubber isolators from GM for when I install it...
First things first, OPEN the box immediately and check for damage.....
