I got a rugged ridge spacer for 40 bucks.... I noticed a difference, but in my head I know it really didn't do anything so that's where I notice the difference... In my head lol, one more thing to make ur mod list a lil longer though!

im a fan of cars, but im no gear head. i dont really even understand the concept of adding one. if a longer air tube did anything, wouldnt they just add a longer tube from the factory?

I think the throttle body thing is a carry-over from the old days when engines had carburetors on them. I can see where certain spacers may improve the mixing of the air and fuel on those engines.
On our engines, the fuel isn't added to the air until a long ways after the throttle body. In fact, it's added at the valves in the head.
