Union

About this product

The Union (#90404-20011) is a pivotal engine-fuel part within the Exhaust Gas Recirculation System (EGR) of Toyota vehicles. Its main role is to connect parts of the EGR, ensuring smooth flow of exhaust gases back to the engine for burning. This process reduces the amount of nitrogen oxide produced, consequently minimizing emissions. Over time, the Union (#90404-20011) can age, become clogged, or break, disrupting the flow of gases which can potentially increase emission levels and damage the engine. It is therefore crucial to replace the Union (#90404-20011) periodically with genuine Toyota parts for compatibility. These genuine parts are supported by Toyota's genuine parts warranty, affording you peace of mind. Ultimately, the Union (#90404-20011)'s function significantly contributes to the overall efficiency and safety of the vehicle by maintaining low emission levels and preserving engine integrity.
