Engineered for demanding heavy-duty diesel service, this C7 series common rail fuel injector (OE 328-2587, cross reference 20R-8067 and 387-9441) delivers OEM-type fitment when correctly matched to the original injector number. Designed for the C7 engine platform and referenced for C9 series applications subject to engine serial number verification, the injector supports precision fuel metering, stable injection quantity, and consistent cylinder output across a wide operating range.

The engineered spray pattern helps optimize combustion efficiency, output power, and fuel economy, while supporting stable idle and smooth acceleration by reducing hesitation and cylinder imbalance caused by worn injectors. It is suitable for high-pressure diesel environments requiring accurate fuel control and is deployed in 950H and 962H loaders, 584 forestry machines, M325D MH and M325D L MH material handlers, marine engines, heavy trucks, fleet diesel engines, and general industrial machinery. Each unit undergoes bench testing for leakage, spray pattern, electrical response, and return flow to ensure consistent field performance.

With a database-ready SKU structure, this injector integrates smoothly into Shopify, WooCommerce, Alibaba, independent B2B websites, ERP, and PIM systems for global aftermarket distribution. Individual replacement is acceptable following proper diagnosis, while set replacement may be considered for high-hour engines. Store units capped, sealed, and dry until installation, and pair with clean diesel fuel and serviced filtration to maximize service life.
