Ferrea Honda D16Z6/Y5/Y7/Y8 30mm 5.48mm 20 Deg S-Flo Stk Flat Head 5000 Series Int Valve - Set of 8

If you're rebuilding the top end of your Honda D16Z6, D16Y5, D16Y7, or D16Y8 engine, new intake valves are a critical part of the process. These Ferrea 5000 Series valves are designed to fit right into your stock D-series cylinder head, making them a straightforward replacement for worn or damaged original valves.

Ferrea uses hardened steel for these intake valves, which helps them stand up to the heat and stress inside the combustion chamber. The 30mm head size is the stock dimension for these engines, and the 5.48mm stem diameter means they'll work with your existing valve guides. The S-Flo design helps improve airflow into the cylinder, which can contribute to better engine performance. They feature a flat head design, common for stock replacement applications.

This set includes all eight intake valves you'll need for a complete engine rebuild. Make sure to check your valve guides for wear and replace them if necessary for proper valve seating and sealing.
