Ferrea Nissan RB26 35.6mm 5.98mm 102.33mm 20 Deg S-Flo Rad Grv +1mm Comp Plus Intake Valve-Set of 12

If you're rebuilding the top end of your Nissan RB26 engine, especially for performance applications, upgrading your intake valves is a smart move. These Ferrea Comp Plus intake valves are designed to handle the demands of a high-performance engine, offering improved flow and durability over stock components. They feature a 35.6mm head diameter, which is 1mm larger than stock, helping to increase airflow into the combustion chamber.

Ferrea uses high-quality materials and manufacturing processes to create valves that can withstand higher cylinder pressures and temperatures. The S-Flo (Swirl-Flo) design and radial grooves on the valve face help promote better air-fuel mixture swirl, which can lead to more efficient combustion. The valves are made from a strong, heat-resistant alloy and are built to last. The +1mm size means they are slightly larger than the factory valves, requiring matching port work for optimal performance, but they are designed to fit within the stock valve guides with proper installation.

This set includes 12 intake valves, enough for a complete RB26 engine. When installing, ensure your valve seats are properly prepared to match the larger valve size for a good seal. These valves are a solid option for anyone looking to get the most out of their RB26 build.
