Do throttle body spacers realy work??Im wondering if its worth it or not to get one.Iv heard they give you more power and gass millage.Is this true???
They are AWESOME paper weights!!
On a carb motor, yes they work
On a FI motor, adds weight to the motor and NOTHIN else!
Please don't waste your money or time!! Save up and get a M1
Ahhh, didn't realize ya had the redheaded step child 3.9...Rooknute do you know if the m1 will fit a 3.9???
