Introducing the Manley Performance 11372-8/11373-8 Race Valves, specifically designed for the Honda and Acura B16A and B18C engines. These are not your average OEM valves Manley Performance VALVEtech Race Valves are engineered for high performance applications, offering significant improvements in durability and flow over stock valves.
Manley VALVEtech Race Valves are CNC-machined from a single piece of 356 aluminum alloy for superior strength and consistency. These valves feature a larger diameter than OEM valves, providing more effective flow for enhanced engine performance. Each valve undergoes a rigorous lapping process to ensure a perfect seal and smooth operation without the need for expensive shims or adjustments.
The Manley Performance Race Valves also include an all-new stem design, featuring a 4140 steel valve stem and a 6Al4V Titanium retained stem. These materials provide superior strength and heat resistance, enabling the valves to withstand the extreme pressures and temperatures encountered during high performance driving. The reinforced stem design ensures that the valves will not bend or fail under the stresses of performance use.
These valves are also suitable for high-lift camshaft applications, and include dish shapes optimized for maximum flow in both intake and exhaust configurations. The intake valves feature a flat top contour with a 1mm quench, while the exhaust valves feature a straight edge seat design for improved flow. The valves feature a reinforced valve spring seat to improve strength and durability.
In summary, the Manley Performance 11372-8/11373-8 Race Valves offer significant upgrades over stock valves for Honda and Acura B16A and B18C engines seeking improved high-performance flow and durability. The CNC-machined aluminum alloy construction, large diameter, and specialized stem design provide enhanced strength and heat resistance for long-lasting performance.
