Has anyone done anything with an throttle body spacers on the new 2013 Black Diamonds? I've got the LTZ with the 5.3L and was thinking of going with the Volant Vortice part number 725253 to go with the Volant CAI with the Powercore Filter that I just ordered. Any insight on whether or not this 2012 version is going to fit(much like the 2012 CAI will fit) and performance and review of this product is greatly appreciated!
