I Have bought Throttle Body Spacers for my last 2 v8's and it seemed to help out 1-3 mpg, I cant find one for the 2012 WK2 5.7. I found one for the 2011. are they the same or should i wait for the 2012 to come out? Also any feedback for Throttle Body Spacers for WK2's
With the huge incentive for all auto makers to improve fuel economy, I'm sure that the engineers at Jeep would have already done this if it actually worked.
TB spacers "work" on carbureted vehicles. Fuel-injected, should, already have the optimal fuel:air ratio. A TB spacer will not effect a fuel-injected vehicle.
This is all to my knowledge and if someone has more knowledge than I, please speak up.
