Garrett GVW-45 Vent Wastegate – blue
The brand new V-Band water-cooled Garrett external GVW-45 Wastegate
CFD optimized, high-temp. stainless body, blue anodized top cover, V-Band flange
Garrett Vent | External Wastegates regulate turbocharger shaft speed by venting exhaust gas around the turbine stage of the turbocharger. CFD optimized design maximizes flow and delivers optimum boost control. Advanced thermal optimization increases durability of the diaphragm. The cap design makes spring changes and serviceability of the entire GVW lineup easier and more reliable to perform.
