In the picture shown above, you can see the dyno charts of this spacer paired with our throttle body spacer and the gains are tremendous. Over 30 ft lbs of torque (in using both spacers) and a significant change in the horsepower curve.The spacer also includes 8 1/8" NPT threaded ports that can be used for aftermarket injection set-ups such as Aquamist. They come with plugs for those just wanting to use the spacer on its own.
