Custom laser piece. 1/4” Black Acrylic tower/injector pod spacer raises the throttle body injector pod out of the bore area the same as the aluminum piece. By doing this it will increase more airflow into the engine for better performance. This piece will withstand 300+ degree temps. The stock throttle body screws will work just fine with these spacers and no additional gaskets are needed when installed with this item. A total of two spacers are required for two throttle bodies. There are two spacers per set which is all that is needed.
