The throttle body spacer realy works! Noticeable increase in horse power, especially going up steep grades. One flaw is the gasket the spacer comes with! Not thick enough to withstand the airflow coming into the V10 engine, so I had a vacuum leak. Had to use the original rubber O-ring from the throttle body instead of the gasket that comes with the kit to stop the vaccum leak.
