FYI... I had problems installing my Z1 intercoolers. I had to bend the brackets to get the intercoolers bolted on. I also had to experiment with switching the direction of the intercooler hoses. The bend in the hose was not exactly in the middle and by switching the direction of the hoses the install went better. Then the ducts didn't line up (were too high). I then elongated the holes on the ducts to lower them, but still didn't get it to line up directly with the front vents. I concluded that I need to make custom brackets to get a good fit.
