The Granatelli Wastegate is a universal performance or fabrication component described by Granatelli as 50MM Wastegate - Traditional Diaphragm Design, Water Cooled. A blow-off valve vents excess charge pressure when the throttle closes, helping control compressor surge in a properly configured turbo system.
Fitment Note: Universal does not mean every installation is bolt-on. Verify dimensions, tubing/hose diameter, electrical requirements, mounting space and companion components before ordering.
