J Replace OE Replacement Lower Injector Isolator - Toyota VVTi

The J Replace OE replacement lower injector isolator for Toyota VVTi engines is a direct match for OEM part number 23291-41010. It is the small insulator that seals the bottom of the injector where it seats in the intake runner, and it is one of those parts that is easy to forget until the injectors are already out and the old isolators are cracked or hardened.

Details

• Direct OE replacement for Toyota VVTi engines
• Matches OEM part number 23291-41010
• Seals and insulates the injector at the intake runner

When to replace

Any time the injectors come out, whether for an injector upgrade, a cleaning service or an intake manifold job, fit new lower isolators. Reusing compressed or brittle isolators is a common cause of vacuum leaks and injector seating problems after reassembly, and the part costs very little compared to chasing a rough idle afterward.

Why J Replace

New OEM pieces for these engines are becoming scarce and more expensive each year. J Replace produces an alternative built to the OE specification at a steady price, so you can refresh a full set without paying dealership money for a rubber part. Please verify compatibility with your specific vehicle and OEM part number before purchase.
