The RDI Performance upgraded BOV kit minimizes boost leaks under higher boost levels and ensures peak boost pressure is reached/maintained. 
 
**This kit is strongly recommended when upgrading to our Stage II RDI Performance Engine Controller.    There are two very different kits.  One is for the Turbo II (8v SOHC) Turbo engine, and the other kit is made specifically for the 16v DOHC Maserati engine.  Please specify when ordering by emailing us with this information so we get you the right kit.
