Ferrea BMW N54 28.5mm 5.96mm 114.75mm 19 Deg Taper Flo +.5mm Trpl Grv Comp Plus ExhValve - Set of 12

If you're rebuilding the top end of your BMW N54 engine, these Ferrea Comp Plus exhaust valves are a solid choice. This set includes 12 valves, each measuring 28.5mm in diameter with a 5.96mm stem and a total length of 114.75mm. They are designed with a 19-degree taper and a Flo+ profile, featuring triple grooves for enhanced performance and reliability.

Ferrea is known for using high-grade materials, and these valves are no exception. They are constructed from a specialized alloy that offers excellent resistance to high temperatures and the stresses found in performance N54 applications. The +.5mm oversized design is intended for engines that may have had valve seats re-ground or require a slightly larger valve for optimal sealing and performance. This attention to detail in material selection and sizing helps ensure these valves can handle the demands of boosted N54 engines.

When installing these valves, it's important to follow the manufacturer's recommended procedures. Ensure your valve guides are in good condition and properly sized for the 5.96mm stems. Having the correct tools for valve installation and checking valve-to-piston clearance after assembly is crucial for a successful rebuild. This set is designed to be a direct replacement for the stock exhaust valves, assuming the necessary machine work has been performed to accommodate the +.5mm sizing.
