Custom Performance Engineering™, Inc., (CPE™) is proud to announce the release of their Blowoff Valve for the Mazdaspeed 3!

Now those with a Mazdaspeed 3 can enjoy the same high quality HKS Super Sequential Blow-off Valve that the CX-7 and Mazdaspeed 6 have available to them.

The HKS Super Sequential BOV kit replaces the factory plastic bypass valve which has been known to rupture under boost. The HKS blow-off valve is machined from billet aluminum and is polished for an attractive and high quality appearance under the hood. Not only is the HKS unit more attractive, it also is more robust, and will not leak under high boost conditions, thanks to its unique pull-type actuation.

The CPE blow off valve kit comes complete, with a high quality HKS “super sequential” Blowoff valve, CPE designed and manufactured adapter flange, and all of the hardware necessary to use this Blowoff valve in either recirculation mode or dump-to-atmosphere mode.

The Custom Performance Engineering (CPE) blow off valve adaptor is machined out of billet 6061-T6 Aluminum. CPE uses a advanced 3D machining processes that most competitors will not spend the extra machine time doing.
