Fuel injector Cup & O-Ring Set | 3VZ-E

Fuel injector Cup & O-Ring Set | Single Cylinder

When performing minor repairs, servicing a single cylinder, or replacing damaged hardware during a top end tear down, don't risk performance-robbing vacuum leaks by reusing worn factory seals. This individual service set provides one fuel injector cup and one matching O-Ring to cleanly restore a single injector seat entry on your intake manifold.

Over years of service, extreme under-hood heat cycles cause the factory plastic cups to become brittle and lose their elasticity. Even a microscopic fracture can lead to unmetered air draw, causing a rough idle or lean condition. Replacing these components during injector service ensures a perfect seal.
