50hp POD Injector 5.9L 12V Cummins 6BT

The Bosch 0432131837-IIS is a new OEM 50hp POD injector, specifically designed as a direct replacement for 1989-1993 5.9L 12V Cummins 6BT engines. It is also compatible with 4BT engines equipped with a VE rotary fuel injection pump. This injector is engineered to be the correct choice for daily drivers, towing applications, and builds aiming for moderate performance enhancements, offering an estimated 50 RWHP increase. Each injector features a 7mm nozzle and includes a 1.5mm nozzle washer (D3920174). It is important to verify the cylinder head nozzle bore size before ordering, as earlier heads (common on pre-1992 models or unserviced heads) may have a 9mm bore that requires a separate sleeve washer (PN D3919358) for proper seating. Cummins updated to the 7mm bore design starting in 1992 to address head cracking issues associated with the 9mm bore. These injectors are sold individually, and a complete engine set requires six injectors. Several accessories are available separately and may be necessary for installation, including return line washers (PN DPE602), an optional 0.5mm nozzle washer (PN D3930324), an injector dust seal (PN D3909356), and the 7mm to 9mm injector sleeve/nozzle washer (PN D3919358) for those with 9mm bore heads. For optimal performance and efficiency with these injectors, the BorgWarner K27 Turbo Upgrade is recommended for 1989-1993 1st Gen Cummins applications.
