im glad you got your problem fixed cheap first off!.... but anyways a intake spacer is a 1\4 inch "phenolic" metal that bolts inbetween your intake manifold and upper intake plenum takes like 20 mins to install.... it says to add 5-10 hp but thats questionable to me but it cools the air comin off your manifold so it increases throttle response quite i bit. thats the only difference i could feel? but it did have great throttle response. you can get on ebay under mustang 96 for 25 to 30 $ and why you are at it you can scrub off the "throttle gum" inside your throttle body "its the black resin in the plenum" and that helped tons in throttle response to
