The Weistec M139 VTA (Vent to Atmosphere) Adapter is designed and manufactured as a complete and simple bolt on solution for attaining the "blow-off" sound that many people are fond of on turbocharged vehicles.  The M139 engine comes equipped with an electronically actuated bypass valve in the turbo compressor cover that recirculates back into the compressor inlet for near silent operation.  With the M139 VTA Adapter, there will be no check engine light as the factory valve is still used, and no tuning or ECU calibration is required.

Key Features:

• 100% Bolt-On Solution

• No Check Engine Light

• Easy 30 Minute Installation

• CNC Machined Aluminum

• Hard Anodized to Military Spec

• Engineered and Manufactured in US
