I've had both the Victor and Pro-Flo on my 493 in the Charger. The Victor with throttle body fits under the hood but I had to build a custom air cleaner. It worked but the intake air temp was quite high so I changed up to the Pro-Flo and CNP. Air intake was moved in front of the rad and reduced the intake charge temperature dramatically. I didn't find any real difference in performance but as stated, the Pro-Flo has small runners.
