    Turbosmart plumb back bypass valve

    Posted by Ben on Jun 18th 2020

    Installation took no joke about a minute while I was replacing my intake. This this sounds AMAZING with an intake, but I'm unsure how it sounds with stock airbox. Great option for people that want a sublet pshhh shifting low and a crazy high pitch sututu when shifting up high. Cant beat the price either. Highly recommend.

    Not Like Others Said

    Posted by Ty on Jan 11th 2018

    Bought this because others said it sounded like stock but didn't leak. Made the most god awful noise at low boost, something akin to a pig squealing while metal chunked, and the valve couldn't hold anything over 10PSI. I hope I just got a dud because I would never recommend this to anyone. Back to the stocker.

    Great Option

    Posted by Danny D on May 26th 2017

    Bought this unit because my OEM bpv was leaking and found it to be a good excuse to go ahead and purchase an aftermarket one instead of another oem because of future mods. Easy install, quiet, but definitely noticeable compared to stock which is great because I didn't want to spend a ton of money on a dual/vta bov.

    Quiet and performs

    Posted by Jachob S. on Sep 23rd 2016

    I bought this because with my mods and tune,I needed something to be able to hold more than the oem bpv could handle. This bolted right on right out the box and had it on my mazdaspeed3 in 15 minutes. No I feel secure that when I run more boost,I won't have a issues.

    Simple install. Looks good. Only had it in for a few weeks so far but am driving her fairly hard as I am currently tuning her and the unit is working very well. I would recommend it.

    2006 Mazdaspeed 6

    Posted by Unknown on Aug 14th 2012

    This thing sounds and performs great! Full stage 2 on MS6 and it sounds just as loud as the hybrid it replaced. Holds boost just fine and the price is awesome compared to most other units.
