I don't know about the MMR TBS but I installed the Jet TB sapcer. It was almost twice as expensive as this one from MMR. You can feel the difference immediately after installation, but from what others have posted, there is very little horse power gain from this mod. What you do get is a noticeable increase in torque.

HP gain is non existant with the TB spacers. Seat of pants feel tells a different story. If you have low RPM flat spots or a throttle lag, it will help quite a bit with that also.

My only concern is the way the MMR ones are designed. If you look at the Jet Performance TBS you will notice a swirl design in the throttle body holes. The MMR is smooth. Looks like about the only thing it would do would be to basically add length to the air path between the throttle body and the intake plenium.

that 5.0 shortblock looks tempting...almost more tempting than a supercharger...........
