A: Please check the model number printed on the side of your injector. This part is designed for the Bosch injector models listed (5230, 5341, 5474, etc.). If your injector model is not listed, please contact us with your injector number for verification.

Q2: What is the installation procedure for this part?
A: Installation requires specialized tools and a clean environment. The orifice plate is a precision component. We recommend installation by a qualified diesel technician. Ensure the injector body is clean and the plate is seated correctly to avoid fuel leakage.

Q3: What is the difference between a 19# orifice plate and other sizes?
A: The “#” number (e.g., 18#, 19#, 20#) refers to the diameter of the orifice hole. The 19# is a specific size used for precise fuel metering. Using the incorrect size can lead to poor engine performance, increased emissions, or injector failure. Always confirm the correct size for your specific engine application.
