ZZP Billet Bypass Valve - K04/Z-series Turbo Supercharger Parts & Kits Silicone couplersOur ZZPerformance billet bypass valve is an upgrade over the stock bypass valve on your K04, Z54, Z57, or ZFR series turbo. The stock bypass is made of rubber and can eventually rip or tear, leading to reduction or lack of performance; our billet unit is sealed via an o ring and uses a machined aluminum plunger to actuate. This billet bypass will also change the "blow off" noise you experience while driving, making it more pronounced. Includes: ZZP
