Tjm
Actually, it doesn't interfere with the roof rack at all. I have this setup on mine with the full size Gobi Stealth rack (no rise option), with the wind deflector installed. The installation procedure is a little more complicated as the snorkel tube runs inside the fender well into the air box (TRD Air Box in my case), requiring the fender liner and fender trim piece to be temporarily removed for proper installation.
The only problem I see with TJM is if you plan on putting on a full size Gobi rack. The snorkel will be in the way.
