This EGR cooler assembly (Type B) is an OEM part for ISUZU NPR, NPR-HD, NQR, and NRR trucks equipped with the 4HK1 5.2L diesel engine from 2007 to 2010. It lowers exhaust gas temperatures before recirculation into the intake system, helping maintain proper combustion conditions and emissions system performance. Manufactured to OEM dimensional and flow specifications, this EGR cooler ensures correct fitment, efficient heat transfer, and reliable exhaust gas flow. Ideal for replacing clogged, cracked, or leaking EGR coolers that may cause fault codes, overheating, or reduced engine performance.
