All EGR Cooler

The EGR (Exhaust Gas Recirculation) valve and cooler are replaced when they become clogged, malfunction, or fail, which can lead to engine performance issues, increased emissions, or even engine damage. 

The EGR Cooler is an auxiliary component that cools the recirculated exhaust gases before they re-enter the engine. This further enhances NOx reduction and improves efficiency by increasing gas density.
