2.080 RF Intake Valves 6.1L Gen-III Hemi

The 2.080 RF Intake Valves 6.1L Gen-III Hemi from MANLEY represent a purpose-built upgrade for serious Mopar enthusiasts and high-performance mechanics seeking maximum flow efficiency in their 6.1L Gen-III Hemi engines. These race-spec intake valves are engineered for applications demanding superior reliability and airflow characteristics, from track competition to street performance builds. This set of eight valves replaces OEM units with precision-manufactured components designed to handle elevated boost pressure and aggressive valve timing events that stock valves cannot sustain.

Constructed from premium stainless steel, the 2.080 RF Intake Valves feature MANLEY's Race Flo series design, optimized for improved gas flow velocity and cylinder filling efficiency. The 2.080-inch head diameter provides the correct seating surface for Gen-III Hemi cylinder heads, while the 0.313-inch valve stem offers OEM-compatible fitment with proven durability under sustained high-RPM operation. The 4.990-inch overall length ensures proper valve train geometry and clearance within the cylinder head assembly, allowing these valves to transition cooler-running air into the combustion chamber with minimal turbulence and maximum volumetric efficiency gain.

Mechanics and engine builders working with forced-induction 6.1L Gen-III Hemi platforms—including supercharged and turbocharged setups—benefit most from upgrading to these precision intake valves. Installation requires professional cylinder head removal and valve replacement using standard valve seat equipment; proper valve timing verification and pushrod adjustment are essential during reassembly. Confirm compatibility with your specific Mopar Gen III Hemi model year before purchase, as some variations may require additional machine work to optimize valve clearances and ensure reliable long-term performance.
