( Brand: Tomei ), ( Manufacturer Part Number: TA303A-HN01A ), ( Type: Valve Set ), ( Fitment Type: Performance/custom ), ( Notes: Valve )
Tomei's Ta303A-HN01A Racing Valve Set is an exceptional upgrade for your Nissan K20 or K24 engine, designed to enhance your vehicle's performance and reliability. This set includes four high-performance titanium valves, specifically crafted for the demanding environment of high-output racing applications.
The Ta303A-HN01A valves are forged from high-strength titanium alloy, ensuring exceptional durability and lightweight properties. This material choice not only reduces the valve's overall weight, thereby reducing the engine's rotational mass, but also provides superior heat resistance and fatigue strength. This results in improved engine response, increased power output, and enhanced thermal efficiency.
The valve stem design of the Tomei Ta303A-HN01A set is optimized for racing applications. The valve stems feature a 5-angle seat, which provides improved sealing and reduces the likelihood of valve seat recession, a common issue in high-performance applications. The valve guides are also fitted with a high-quality, low-friction coating, ensuring smooth operation and reducing the risk of engine damage due to excessive heat or wear.
The Tomei Ta303A-HN01A Racing Valve Set also includes high-quality springs and retainers. The springs are made from a high-tensile material, ensuring proper valve control even under high-boost conditions. The retainers are designed with a strengthened locking mechanism to prevent valve float and maintain proper valve position.
In summary, the Tomei Ta303A-HN01A Racing Valve Set is an excellent choice for anyone looking to improve their Nissan K20 or K24 engine's performance. Its combination of high-strength titanium alloy construction, optimized valve stem design, high-quality valve guides, and high-tensile springs and retainers makes it a reliable and powerful upgrade for your engine.

The intake valves are made using SUH35 HEAT RESISTANT STEEL which is more commonly used to make exhaust. These are then coated with a special formula that further improves the valves' resistance to heat, wear and corrosion. Not available on some model's. Fa20 The wasted stem allows a greater volume of air/gases to enter and exit the combustion chamber as valve extends.
