The Splitter valve is a remarkable valve that gives a combination of blow off and recirculation valve operation all at the same time and has been specifically designed for the many turbo engined applications that operate metered airflow management systems.This means you get all the noise of the blow off valve whilst retaining the compatibility with the recirculation requirements of the engine management system. The Splitter valve is also adjustable to suit your engine and can be converted to be totally recirculating if you ever require a stealth approach!Key Features:Developed for the VAG 1.8/2.7 Turbo applications.Adjustable To SuitColor:BlackSilver
