Not sure how many discrete pieces make up a factory CAC pipe for the 6.7. Parts are glued together, hose clamped together, part of it is silicone, I think some of it is ABS. I think the factory tube is 5 different pieces. So much that can wrong with this thing. In my case, like many others, it was the plastic connection right at the throttle body that broke and the whole pipe blew completely off the throttle body. I've seen that same plastic pipe split and blow a hole in the middle, yet remain connected to the throttle body. Others had the plastic pipe on the intercooler side break.
Nothing wrong with KISS - but Ford didn't for some reason. I really doubt this was how it was originally engineered. Seems like accountants, productivity engineers, and just of out college design engineers all partied together to get to the final design.
