In-car volume-adjustable blow-off valve!

A WORLD FIRST in blow-off valve technology, the Deceptor Pro is based on the patented volume adjustable Stealth FX blow-off valve, but advances the design even further, featuring an industry world first: electronic proportional in-car adjustment of blow-off valve volume!

Remote, proportional blow-off valve volume control – from silent to loud, and anywhere in between

Modern and compact in-car BOV ‘volume controller'

Volume adjustment mechanism driven by a high-torque electric motor

Durable, low friction gear train supported by sealed precision ball-bearings

Supplied with all parts and wiring necessary to have it up and running quickly and easily

Ertalyte™ piston ring – to maintain the integrity of the vacuum signal, without the maintenance issues of an o-ring

Acetal™ piston seat – for a positive seal under boost and a long, maintenance free life

Lightweight piston – for fast valve response

360° rotating vacuum nipple - for neat installations

Low profile, user friendly spring adjustment mechanism – no tools required

The WRX Deceptor Pro blow-off valve is a 'bolt-on' fit for late-model Subaru WRX and STi models (see below for specific applications).

It doesn't require any adaptors, extras or modifications - just remove the factory BOV and bolt it on!

The Deceptor Pro allows you to go from silent and stealthy to ear shattering in a matter of seconds whilst staying firmly put in your drivers seat!

It is a little known fact that the late-model WRX factory blow-off valve is actually designed to leak at boost pressures exceeding the factory level. Replacing it noticeably improves throttle response, and is definitely recommended in applications where the boost has been raised.

Suits:
MY01-07 WRX (MY02-07 in the U.S.), NOT including the new body shape.

MY02-08 STi, which DOES include the new body shape.
