About this product
When outlet valve performance matters, the TRW Engine Component S4280 delivers — built to the same dimensional and material standards as the original part it replaces. The part is built to the following specification: Length [mm]: 123, Plastic mm, Material: 67, Supplementary Article/Info 2: 732, Supplementary Article/Info 2: 729, Valve Head Diameter [mm]: 29 mm. Each dimension is checked against the OEM reference to ensure the component seats and functions correctly first time. Compatible with HONDA vehicles; use the vehicle selector above to confirm exact fitment for your make, model, and engine variant. Fitment data is sourced from TecDoc, the authoritative European parts catalogue. This part supersedes original equipment references: 0730OSVAT, 14721-PT3-A00, 14721-PT6-A00, 631 VA 31135 100 and 3 more. Matching these numbers confirms a like-for-like replacement with no loss of function.

All parts are sourced from authorised distribution channels and carry full manufacturer traceability — you receive exactly the same component supplied to professional garages and dealer workshops.
