5.0 Mustang and Superfords did an install on an SN95 in their November 04 issue and it says "...CDC now makes a shaker for your '94 or '95 GT ( or GTS), but only if it still wears its factory intake manifold . It's also routed to the stock airbox. This was on a 94/95 so I don't know if it applies to newer stangs or not. The intake manifold part yes I'd imagine but I'm not positive about the airbox.
