ModalWorks M177 C63 & GLC63 Mechanical Blow-Off Valve Kit

ModalWorks M177 C63 & GLC63 Mechanical Blow-Off Valve Kit

Upgrade the factory electronic diverter-valve system with a performance-focused mechanical blow-off valve conversion for Mercedes-AMG C63, C63 S, GLC63 and GLC63 S models equipped with the M177 engine.
