• 1Y manifolds are only good for TDI/AAZ heads tho. D port manifolds on 0 port heads do not flow well at all..

  i would have gone with ALOT BIGGER tubing from the front to the air box.

  
  Lower air velocity also means less energy to push water into the intake.

• That is neat. I think the raintray from the GTI is going to become that factory CAI on my car

  It's on my 1981 Caddy. I suspect this part is from a Jetta of the same vintage.

• My research shows 82-84 for Jetta implementation like you have; 85 up had a piece that fit a hole in the side of the fender and then to the air cleaner. The same design that you have was used by after market and the cost increased accordingly. Thanks.
