I haven't had it installed very long but did notice an increase in throttle response...not sure of the mpg. but am happy with it it so far

They seem to work. The Volant cold air intake & this seem to have lowered the rpm buy about 200 @ 65 MPH. the hill climb in cruse is really noticeable, a whole lot smoother, again not as abrupt down shift. I chose the spacer because of the air intake. The install is straight forward. Auto Anything has the best deal & is a fast shipper. I hope the info. is a help in your decision.
