Supertech Black Nitride/ Inconel Valves for G16E-GTS Toyota GR Corolla

Maximize the performance of your Toyota G16E-GR with our high-performance racing intake and exhaust valves. Crafted from a single piece of forged material, our intake valves undergo a rigorous two-step forging process to enhance grain flow and strength. Each valve is precision CNC-machined in multiple stages to ensure perfect dimensions and peak performance. For added durability, we apply advanced heat treatments for stress relief, followed by a specialized nitride hardening treatment or coating based on your specific needs. Our precision grinding and patented Superfinishing technique guarantee a flawless surface and precise dimensions. Upgrade your Toyota G16E-GR with our racing intake valves, engineered for top-tier performance.

The "Black Nitride" is a hardening treatment that is applied to the whole valve whereas the chrome coating is only applied to the stem. The microhardness is higher than the stainless steel base material, keeping good ductility beneath the hard nitrided layer. Microhardness is 800HV minimum.

The Black Nitride surface finish is smoother than with chromed stems, having less friction between stem and guide. The higher the engine speed the bigger the power loss due to internal engine friction! The Black Nitride reduces this power loss due to less valve-guide friction.
