Mazdaspeed HKS BOV
The MZR 2.3 DISI vehicles use a by-pass-valve (BPV) system to recirculate excess pressure from the turbo when the throttle closes. When upgrading from the factory valve – it’s important to maintain this system. Our kit includes everything that you need to get the added durability of a Mazdaspeed HKS BOV, but with the recirculating hardware needed to keep the factory system happy. *Does not include BOV.
