50mm Blow Off Valve All Black — Blemished Clearance
Performance at a discount — same function, a few battle scars. This 50mm blow off valve all black blemished clearance unit from Black Sheep Industries (BSI Inc.) delivers full turbo performance at a fraction of the cost of a flawless piece.
Why This BOV Belongs in Your Build
Fully Functional — Full Stop
Every scratch and dent is cosmetic only. The valve operates exactly as it should — no compromises to boost holding, cracking pressure, or daily reliability.
50mm Sizing
The 50mm diameter is a popular standard for a wide range of aftermarket turbo setups, making this a practical fit for street builds, track cars, and performance applications across the board.
All-Black Finish
The blacked-out aesthetic looks clean under the hood regardless of the blemish — and once this thing is tucked into your engine bay, odds are no one's getting close enough to notice anyway.
Clearance Pricing, Not Clearance Quality
At $240 CAD, you're getting a genuine BSI Inc. blow off valve — made by a Canadian performance brand — without paying the premium for cosmetic perfection. Turbosmart and Forge charge $300–$450+ for comparable units, new in box.
Ships from Canada
Built and shipped domestically, so North American builders on both sides of the border can get their hands on a quality BOV without the wait or the customs guesswork that comes with overseas imports.
If you're building a turbocharged setup and every dollar counts, this is the grab — real performance hardware, honest pricing, and zero apologies for a couple of cosmetic scuffs.
