Ferrea Nissan RB25DET 35.12mm 5.97mm 86.7mm 15 Deg S-Flo +1mm Comp Plus Intake Valve - Set of 12

If you're rebuilding the top end of your Nissan RB25DET engine, these Ferrea Comp Plus intake valves are a solid option. This set includes 12 valves, each featuring a 35.12mm head diameter and a +1mm oversized stem, designed to fit your engine's specific needs during a rebuild. They are built with Ferrea's S-Flo technology, which aims to improve airflow into the combustion chamber.

These valves are constructed from high-strength stainless steel, chosen for its durability under the high temperatures and pressures found in performance engines. The 15-degree seat angle is a common specification that works well with many cylinder head designs. Ferrea is known for making well-built internal engine components, and these valves are no exception, offering a good balance of performance and reliability for your RB25DET build.

When installing these valves, ensure your valve guides and seats are properly prepared to match the +1mm stem size. This set is designed for the RB25DET engine, so double-check your specific engine code to confirm fitment for your project.
