The Plumb Back is a fully recirculating valve, so all vented air is routed into the vehicle's intake. The Plumb Back offers all the benefits of a Turbosmart BOV, but with quiet operation, it doesn't attract any unwanted attention.

The Shortie offers improved valve response thanks to its lightweight piston, while its precision billet construction gives better sealing and durability and up to 30psi boost handling capability. That sharper valve response means boost builds faster, while the better sealing means it holds on longer, giving you more power throughout the rev range even in an otherwise standard car.

Quality is at the heart of every Turbosmart product, so the Shortie not only improves the performance of your EcoBoost engine but it also guards against potentially damaging compressor surges - and will do so for a long time.
