Toyota 232910H020 — Injector Vibration Insulator
Overview
Fuel injector vibration insulator Toyota 232910H020 seals the fuel injector seat within the intake manifold housing and dampens engine operating vibrations. The component prevents unmetered air ingress into the intake tract and fuel leakage around the rail interface. Manufactured from fuel-resistant fluororubber FKM, it withstands thermal fluctuations from -40 °C to +150 °C without hardening or splitting. Main specifications include inner diameter 9.5 mm, outer diameter 16.0 mm, and thickness 7.5 mm. OEM reference part number 232910H020 matches original factory seat tolerances precisely for direct replacement during fuel rail service.
Fitment includes Toyota Camry ACV30, ACV40 2.4, RAV4 ACA20, ACA30 2.0, 2.4, Avensis AZT250 2.0, Highlander ACU20 2.4, Solara 2.4, and Previa models produced between 2000 and 2010 fitted with 1AZ-FE, 2AZ-FE, 1AZ-FSE, and 2AZ-FSE petrol engines. Replacement is required during injector ultrasonic cleaning, fuel rail removal, or when air leaks cause lean mixture fault codes. Over time, heat exposure causes the original rubber insulator to dry out, shrink, harden, and crack. Faulty seat insulation results in rough idling, engine misfires, and vacuum leaks. Installing a new insulator restores vacuum tight sealing, reduces injector noise transmission, and protects the injector body.
