Tomei TD03-20G TRB (35.15mm Intake Valves & 31.15mm Exhaust Valves) for Nissan SR20DET Engine

The Tomei TD03-20G TRB (35.15mm Intake Valves & 31.15mm Exhaust Valves) is an exceptional upgrade for Nissan SR20DET engine owners who seek improved engine performance. Tomei, a renowned name in the world of automotive aftermarket parts, designs and manufactures these high-performance valves to deliver enhanced power output, better engine response, and increased durability.

These valves are engine-specific, designed for the Nissan SR20DET engine. The intake valves measure 35.15mm in diameter, while the exhaust valves measure 31.15mm, delivering optimal flow for this particular engine. The valves are made from high-quality materials, including the valve stems made from SUS304L and the valve heads made from SUS4130M. These materials ensure superior strength, durability, and resistance to heat and corrosion.

The intake valves feature a unique NaNoFlowed surface finish. This advanced technology involves coating the valves with a thin layer of nanometer-sized ceramic particles. This process reduces the valve's surface roughness, minimizes friction, and enhances the flow of air into the engine, thereby improving combustion efficiency and overall engine performance.

The exhaust valves feature a precise shape and diameter designed for optimal exhaust flow. This design helps to ensure efficient exhaust scavenging, reducing backpressure in the engine, and allowing for a more efficient power output.

These valves are designed to work seamlessly with the OEM camshaft and valvetrain setup of the Nissan SR20DET engine. However, for optimal performance, it is recommended to use them in conjunction with a high-performance camshaft.

The Tomei TD03-20G TRB intake and exhaust valves are an excellent choice for SR20DET engine owners seeking to enhance their engine's performance. They provide a noticeable increase in power output, improved engine response, and increased durability. With their high-quality materials, advanced technology, and engine-specific design, these valves offer a reliable and effective upgrade for your Nissan SR20DET engine.
