Product Description

The Turbosmart TS-0203-1221 Kompact Plumb Back is a full recirculating blow off valve designed as a high-performance replacement for factory plastic Bosch or Denso bypass valves. The Plumb Back system recirculates all excess boost pressure back into the intake system, providing stealthy operation ideal for enthusiasts who want the performance and reliability benefits of a quality BOV without the audible vent-to-atmosphere sound. Billet aluminum construction with an O-ring sealed piston design delivers superior structural integrity and excellent boost holding capability up to 30+ PSI - far exceeding the durability of factory plastic valves that are known to crack under increased boost and heat cycling. The fully sealed design is perfect for vehicles with sensitive MAF/AFM systems and prevents foreign matter from entering the system. Superior flow and fast valve response reduce turbo lag and eliminate compressor surge. The stealth black finish blends seamlessly into any engine bay. Includes green spring rated at -15 InHg pre-installed. Designed and manufactured in Sydney, Australia. Not legal for street use in California.
