i know you can modify a second gen intake to fit a 3rd gen but i dont think the other way around. plus you want to say away from banks. its dyno proven to flow less air than a stock manifold. if you really want a good intake manifold look up Byrd's diesel off of ebay. there made to order with 3 ports and powdercoated the color of your choose for under $200. i have one its a real quality American part
