i want to get a 65mm throttle body but dont know if i need the egr spacer as well do i buy both or what?

Yeah you need to buy both, one without the other would be pointless, or unless you have a cobra intake with a built in egr. If you're just putting it on a stock intake you're not going to see any real power gains.
