I routed mine over, once everything was in place and tightened down, it has about 3/8" clearance above the arm.
The one issue I ran into was the line from the AVCS fitting to the filter was a little snug routing around my SPT intake. Not enough to prevent installation, just something that worried me a bit. Obviously you can't make one of these specially for every possible intake on the market but even an extra 1/2" on that line would have made things way easier.
Still a great product and very happy I purchased it!
