Product Info
The Focus RS Shortie uses a billet aluminium body and an individually matched brass piston, with enlarged flow ports designed for the RS application. The adjustable cap sets spring preload.
TS-0203-1064 Dual Port divides discharge between recirculation and atmosphere, giving a more audible release under boost. TS-0203-1264 Plumb Back returns the discharged air to the intake for a quieter result.
Each kit includes one valve, a model-specific boost-reference adapter, mounting hardware, vacuum and PCV hoses, fittings, blanks, clamps and cable ties. This is a vacuum/boost-referenced installation, not an electronic Kompact EM valve. The manufacturer procedure includes adapting the factory PCV plumbing; professional fitting is recommended. Confirm the Mk3 RS 2.3L application and check local requirements before selecting atmospheric venting.
