Fuel Injector Cup Set
When performing a top-end rebuild, servicing your intake manifold, or upgrading your fuel system, don't risk performance-robbing vacuum leaks by reusing worn factory hardware. These fuel injector cups press directly into the intake manifold plenum runners, providing a clean, perfectly sealed seat for your OEM Toyota injectors.
Over years of service, extreme under-hood heat cycles and age cause the factory plastic cups to become brittle and fatigue. Even a microscopic crack or slightest loss of elasticity can lead to unmetered air draw and rough idling. Because the 3.0L V6 intake manifold requires significant labor to remove, replacing these components as preventative maintenance while the top end is disassembled is highly recommended. This comprehensive 12-piece overhaul kit provides everything needed to fully restore your engine's injector seats.
