I spoke with him earlier. It is a tight fit but as long as you make sure the tube is laying on the shroud pretty much you'll be good. I just did a short drop and it closed fine. He was a little nervous but I'm sure with my advice he will be fine on the reinstall.
You need to make sure the transition hose is fully angled on the tube. it needs to be slid on as far as it will go on the bottom. the top section of the hose edge will line up with the ledge on the plastic tube. When you push the tube on to the throttle body make sure it is pressed all the way on the throttle body. then while pushing the elbow forward and down onto the fan shroud, tighten the TB clamp.
The coupler comes pre installed and clamped tight on the tube for that reason. We will add the note in the instructions though, thank you.
Oh, yes, one side is 4" and one side is 3.5" We can send another coupler if you want. It might be faster to find one locally though.
No prob, just let us know!
Once it's connected it's not going to untwist mine was like that day 1 and it's still connected. [emoji106]
