2005 Subaru Impreza WRX STi showing HKS SSQV Blow-off valve

*Edit* I sold the car and don’t really care to answer questions about it but feel free to use the comments for discussion on the topic. Thank you all for the 325,000 views! An under the hood look at the HKS SSQV BOV before it was recirculated on my 2005 Subaru Impreza WRX STi. Although the video may make it appear to be, this was not a cold start.
