I personally don't have one, but i know the angle you need is 22* or 45* pipe. Im just neglecting it because i dont know what i need, and my engine rocks back and forth alot on lope idle, and i dont know if the filter would stay put if i took the flex pipe out and used an aluminum pipe.
i used the 2 ends of the stock rubber tube and cut them off at the first rib, then i took a piece of 4in alluminum exhaust tubing i had, a couple of band clamps and inserted the alluminum pipe into the two cut rubber ends. and stuck a 46637 on the end. it works like a charm---- for me, i just didnt like the ribbed portion of the stock intake hose, as all performance intakes go, smoother is better, now, have i increased airflow, maybe a hair or two, or maybe not at all, but when i hit that sweet spot and that turbo whistle starts bellowing through that alluminum pipe, you know it........
