Ferrea Infiniti VR30DDTT 28.50mm 5.46mm 97.50mm 25 Deg Taper Flo Stk Super Alloy Exh Valve-Set of 12

What you get in this box is a set of 12 Ferrea F2411P exhaust valves, specifically made for the Infiniti VR30DDTT engine. These valves measure 28.50mm in head diameter, have a 5.46mm stem, and a total length of 97.50mm, with a 25-degree taper. They are constructed from a super alloy, which is a strong material chosen for its ability to withstand the high temperatures and stresses found in performance engine applications.

Ferrea uses this super alloy for its exhaust valves because it offers improved resistance to heat and wear compared to standard materials. This is especially important for exhaust valves, as they are exposed to the hottest gases exiting the combustion chamber. The 25-degree taper on the valve face helps create a solid seal against the valve seat, which is crucial for maintaining compression and preventing leaks. These valves are designed to fit stock valve guides and retainers, simplifying the installation process when you're rebuilding or upgrading your engine's top end.

When you're working on the VR30DDTT engine, especially if you're aiming for improved performance or rebuilding after significant mileage, using high-quality valves like these Ferrea F2411P units is a smart move. They are built to handle the demands of the engine, ensuring reliable operation and helping to maintain the integrity of your cylinder heads under load. Make sure to follow the manufacturer's installation instructions carefully when fitting these valves to your engine.
