MACH 2 ATMOSPHERE UPGRADE KIT TO CONVERT T9120 FROM RECIRCULATING TO ATMOSPHERE VENTING BOV. CONSISTING OF TRUMPET, SPRING AND PLUG. There is a harder spring supplied in this kit, as the valve needs to remain closed at idle when venting to atmosphere. This prevents stalling and backfiring.  

You asked, we delivered. Many times we have been asked for a replacement trumpet that gives a different sound, and here it is.
