    <font color="red"> </font> I put the araid on my 90 TBI and my gas milage went up 1 mile per gallon ( upper 9's to upper 10"s) I would say after 4-5 tanks it paid for itself. Giddy Up!! /forums/images/graemlins/peace.gif /forums/images/graemlins/burb.gif

    I've seen some say they do and some they don't...I never tried it though since it would be going on my mom's truck. It seems to me like the 1" spacer is the way to go though if you are gonna do it.

    Have one, installed it, works good.

    do either the 1" spacer or the injector spacer, installing both dont seem to do as much for ya.

    Turbo City spacer....

    I went from 13.2 to 14.1 on my 93 498 powered C2500 from San Diego to Lake County Ca with mine and then added another .6 with a K&N FIPK....

    i've got the spacer, the K&N off-road air filter, edelbrock headers, extreme flow K&N top air filter, low temp thermostat. all these together work very well. it opens up the top end, opens up the bottom end and get it more gas to open up a can of whoop a$$. and i still get 13.5 running 38's w/ 3.73 gears on the highway @75mph.

    Have the same setup but have JBA headers and flowmasters, plus the flex-a-lite duel electric fans, really sets the horsepower free
