Nissan CP 34mm Intake Valves 6mm 103.13 OAL

The Nissan CP 34mm Intake Valves 6mm 103.13 OAL from FERREA are precision-engineered components designed for builders and mechanics focused on high-performance cylinder head modifications for Nissan platforms. These intake valves are essential for any engine rebuild, porting project, or performance upgrade where OEM components may not meet power objectives. Whether restoring a vintage Datsun or modernizing a contemporary Nissan engine, selecting quality valves is crucial for flow efficiency and engine longevity.

FERREA valves are manufactured to exacting tolerances using premium alloy steel, ensuring consistent performance across thermal cycles and high-RPM operation. The 34mm head diameter provides optimal flow characteristics for intake applications, while the 6mm stem diameter maintains structural integrity under aggressive valve train loading. The 103.13mm overall length (OAL) specification ensures proper fitment with your cylinder head's intake port geometry and rocker arm architecture, preventing valve-to-piston interference and guaranteeing correct installed height for accurate valve timing.

These valves are ideal for Nissan CP-series engine builders, enthusiasts performing head porting work, and shops specializing in Japanese performance modifications. Installation requires precise valve seat machining and spring rate verification to match your specific cam profile and target RPM range. Proper selection and installation of these valves can significantly enhance engine performance and reliability.
