Q: What do I need to bolt in a 1997 f250 7.3?

all you need is a 4"to 4" exhaust adaptor from your local Napa,fleet farm whatever. remove stock air box, zip tie senser, use stock clamp from stock rubber tube and find a 4.5 inch clamp for the filter or do what I did on the last 4- 7.3s I've done and use elec. tape to seal filter to pipe. take yer time make it look good and its good to go

Q: What do I need to bolt in a 1997 f250 7.3?

You need a 45° PVC elbow, 4" diameter, and 2 big hose clamps. And remove your old air box, all of it.
