Description
If you’re running a high-output LS1 engine, your stock intake valves are a bottleneck—they can’t sustain the flow rates and thermal loads of serious power. Manley’s Race Series intake valves are engineered for sustained high-RPM operation and aggressive valve timing, delivering the reliability and flow characteristics your build demands. This set of eight stainless steel valves gives you the precision component quality required for turbocharged, supercharged, or naturally aspirated competition engines.
