The initial plans weren’t to develop a new plenum but we had no other choice as the BPS TWIN 73mm T/B is just too large to fit the stock ”13 TVS plenum. Even ported, there is not enough meat to mate it with our T/B and it is the sole reason why we came out with one.

This plenum is a direct bolt onto your ”13-14” TVS. It does not require any porting to match your supercharger inlet but the added material gives you plenty to work with if you wish to open it up even more.

A straighter short radius and larger inlet for the T/B side, this plenum will help direct the airflow with less restrictions.

- Same cast aluminum finish as OEM

- Available in Textured Black or Silver.

*NOTE* 2007-2010 models will need an extra evap fitting. (Two in total, one which is included with the oversized plenum)
