NEW OEM CAT 375-8487 Exhaust Manifold – Heavy Equipment Diesel Engine

For sale is a NEW, genuine Caterpillar OEM exhaust manifold, CAT part number 375-8487, engineered for high-output Caterpillar diesel engines operating in extreme-duty construction and mining environments. This is a factory OEM casting, not aftermarket, rebuilt, or offshore reproduction.

This manifold is manufactured from high-density, heat-resistant cast iron specifically designed to survive extreme exhaust temperatures, rapid thermal cycling, and constant vibration. Precision-machined flanges and port surfaces ensure correct exhaust gas flow, leak-free sealing, and proper turbocharger efficiency, protecting engine performance and emissions integrity.

OEM CAT exhaust manifolds are critical for preventing warping, cracking, exhaust leaks, and turbo damage commonly caused by inferior aftermarket parts. This component is a direct OEM replacement, designed to install without modification and restore factory exhaust system performance.
