this is my first and last post here. I own a Dodge Dakota R/T but I have a question about mustangs. I know that, for a proven fact that Throtte body spacers DO NOT work on our trucks (2.5L, 3.7L, 3.9L, 4.7L, 4.7L HO, 5.2L, 5.9L) and have shown a lost in power and torque, but there is this ford guy at work, (not a mustang owner, hasn't hot rodded ****) that says they do work period on FI cars. I want to if they do work on any Multi Port Fuel Injected mustang motor or any ford motor that uses FI. so do they? Thanks!!!

 

I do not have one but I have heard by many people that they are proven to show small power gains and gas mileage.
