Intake to Throttle Body

I just installed a K&N FIPK II (which is friggin awesome) and have it attached to the stock throttle body. I plan to pick up an Accufab 70 or 75mm Throttle body with plenum. My only question is how do I hook up the K&N intake to a bigger throttle body? I'm really looking to go to the 75mm throttle body if its possible.
