Do throttle body spacers work on fuel injected engines?
it can rob you of low end horse power and fuel mileage because those work best sometimes at higher speeds than lower speeds,i had one on my 99 model truck and took it off an gave it away for the simple fact that it made it worse rather than better,some people get good gains from them but most don’t,depending on the condition of the engine it can hurt it more than it helps it,good luck.
