             Top insert for changing opening size  XR1  

      TBS XR Race Inserts are crafted from billet aluminum in an array of sizes.  Meant to change when boost is activated, a smaller opening boosts quicker and a bigger opening produces more boost on the top end.  A quick way to tune your blower at the track, these inserts are available only for the race series blowers.
