    Default Does a throttle body spacer actually increase MPG???

    Is a throttle body spacer worth spending the money to increase MPG or is it a waste of money.

    Which type should I get that is inexpensive? Are they all the same? Prices range from 50 to 100

    Complete waste of money. Spacers are only good on carburetors.

    It did on mine. This has been talked about before those that don't have them say no those that have them say yes. I did not do a before and after mpg test but what I can say is when I go to the beach I always go to the same spot same route. Before 3/4 tank round trip after a little more than a 1/2 tank. I'm not saying this just because I have one. I would be the first to admit that I made a mistake by installing one if I did not see some kind if incress.

    So if I get one which inexpensive one should I get. Even a 2 MPG increase would pay for it....
