    Sounds so good  4 months ago

    Added this to the CPE exhale kit for my Focus ST. Sounds so good, especially with the gold fin added. Install is a little bit of a pain. Just have to get some quality snap ring pliers. The ICON kit from harbor freight worked perfectly for me. The cheapies just don't cut it.

    Awesome Sound  7 months ago

    This BOV is perfect to get that classic sound everybody loves. I've had mine on for 4 years and it performs great. Only complaint about it is the clear coat seems to flake off after a while.

    HKS SSQV vs TiAL Q 2 years ago
    5out of 5stars

    The product is great and I've used this BOV on my Supra for 6 years without issues. However in comparison to the TiAL Q, there is noticeable compressor surge at low pressure relief in comparison to the TiAL Q, due to the primary and secondary valve operation on this HKS BOV. For a detailed description reference my video: https://youtu.be/9mExdJ4ebSU

    HKS... the legendary BOV sound no one has copied. This is the 7th one of these I have put into one of my cars. Hands down my favorite BOV.
