This is a set of professionally remanufactured 4-hole Bosch III UPGRADE injectors that directly replace the original stock 53007232 injectors, providing improved fuel atomization for smoother engine performance, better efficiency, and more consistent operation.
 
All injectors are thoroughly cleaned, tested, and flow matched using ASNU professional equipment to ensure they meet or exceed OEM performance standards. We are a certified ASNU service center.
 
Why choose OEM remanufactured injectors?
Unlike many aftermarket injectors on the market, genuine OEM injectors are built to a higher standard and designed specifically for your vehicle. When properly remanufactured and flow tested, they provide more reliable performance, better consistency, and longer lifespan compared to low-cost alternatives.
 
Flow Matching
The ECU controls your injectors as a set. If injectors are not closely matched, some cylinders can run slightly rich while others run lean.
All of our injector sets are flow matched to within 3% or better, which meets or exceeds the typical factory standard of approximately 5%.
For customers looking for the highest level of precision, we also offer an optional 1% flow matching upgrade with documented test results.
 
Quality and Testing Process
Each injector goes through a comprehensive remanufacturing process, including:
 
Electrical testing (OHM test)
Full disassembly and inspection
Multiple ultrasonic cleaning cycles
Reverse flow backflushing
Leak testing under pressure
Spray pattern analysis
Flow rate testing and matching
Reassembly with new internal components (filters, O-rings, seals)
Final quality control inspection
 
Lifetime Warranty
All of our injectors are backed by a lifetime warranty. If the injectors ever become clogged or fail under normal use, we will clean, test, and service them to restore like-new performance.
 
Fitment
 
This set fits the following vehicles:
 
1991-1995 Jeep Cherokee 2.5L I4
1991-1992 Jeep Comanche 2.5L I4
1991-1995 Jeep Wrangler 2.5L I4
 
Replaces part number: 53007232
 
Important Note
To ensure long-term performance, we recommend replacing the fuel filter and confirming the fuel system is clean prior to installation. Contamination in the fuel system is the most common cause of injector issues.
 
This set directly replaces the stock Siemens part number 0280150804. The injectors will look different from your stock injectors, but they have the same fitment from seal to seal and same flow rate as the stock injectors.
