4.6L 2 valve stock throttle body spacer suggestions

[Sgt.bustacap]

So everywhere I seem to look its either for the v6 or it says the 4 valve I need a recommendation for the throttle body spacer for the the 2valve 4.6L V8 if anyone knows I'd really appreciate it

Or should I maybe just get a bigger throttle body instead best bang for my buck is all I'm tryna get and maybe a lil better mpg since I already got the k n n cold air intake that gave me 2-3 mpg
