Mahle FluidPRO Valve Cartridge S1, ATX-3+Boost (#025-80375-03)
Mahle FluidPRO Valve Cartridge S1 is the genuine MAHLE service part — the S1 valve cartridge — the seated valve that opens and closes the S1 circuit on the ATX-3 manifold.
A cartridge that no longer seats cleanly lets fluid past when it should hold — erratic exchanges trace straight to it. The factory cartridge seats the way the manifold was machined for.
