Calibrated With Precision And Tested For Every Load

The Industrial 0986435521SE-IIS is not your average remanufactured injector, it’s a complete rebuild performed in-house using OEM stock bodies and all-new factory-grade internals. Every unit undergoes an extensive multi-point test process that simulates real engine conditions, including resistance testing, leak checks, purge cycles, and performance verification at idle, mid-load, and full-load ranges. Each injector is flow-matched and balanced more precisely than the original manufacturer’s standards, which helps ensure consistent fueling across all cylinders and maximizes engine efficiency. The set includes a new copper crush washer and o-rings to ensure a proper seal on installation, which minimizes the chances of leaks or fuel system issues down the line.
