The GSC Power GSC2004-8 intake valve is a high-performance aftermarket upgrade specifically designed for the 4G63T engine found in various Evolution models from 1991 to 1998, including the DSMEvos. This intake valve is an excellent choice for those seeking to enhance the breathing capacity of their engine and improve the overall performance of their vehicle.
The GSC Power intake valve for the 4G63T engine is a 35mm unit a significant increase from the 31.5mm stock valve diameter. Increasing the intake valve diameter allows for a larger volume of air to flow into the combustion chamber, leading to increased air intake and better combustion. Consequently, more fuel can be burned, resulting in a performance boost.
The GSC Power intake valves are CNC-machined from high-quality billet material. This manufacturing process allows for precise dimensions and excellent fitment. Additionally, the simple design ensures easier installation, as no requiring valve guides, valve seals, or springs. These components are reusable, and the intake valve comes with new O-rings and shims.
The GSC Power 35mm intake valves feature a honed, polished finish. This smooth, mirror-like surface reduces turbulence and friction, allowing the valves to operate more efficiently. Together with the valve's symmetrical design, the airflow inside the intake port is optimized, resulting in better cylindrical scavenging.
Moreover, the GSC Power intake valves are compatible with regular unleaded gasoline and commonly used racing fuels. You can confidently upgrade your engine with this intake valve setup no need for special modifications or premixing fuel.
In summary, the GSC Power GSC2004-8 35mm intake valve provides numerous benefits for the 4G63T engine in DSMEvos, offering improved breathing capacity, increased performance, and a smoother operating engine. With its durable, CNC-machined design and easy installation process, this aftermarket intake valve is an excellent choice for enthusiasts and racers striving to enhance their vehicle's power output.
