Supertech Toyota 5VZ-FE Black Nitrided Intake Valve – Set of 12
The Supertech TIVN-1040-12 Black Nitrided Intake Valves are a premium performance upgrade for the Toyota 5VZ-FE 3.4L V6 engine (found in Tacoma, T100, 4Runner, Tundra, etc.). These valves feature a black nitride coating on high-grade stainless steel for exceptional wear resistance, reduced friction, and improved heat dissipation. The nitride treatment hardens the surface, increasing durability under high-RPM, high-heat, and boosted applications while maintaining excellent flow characteristics. Sold as a complete set of 12 (full intake side), these valves are ideal for naturally aspirated, supercharged, or turbocharged 5VZ-FE builds seeking longer valve life, better sealing, and reliable performance with aggressive cams or higher lift. Precision-machined in Europe for perfect fit and consistent quality in motorsports and high-performance engine applications.
