FAQ

Q1: How do I verify this injector (0445120219) is correct for my engine?

A: Please locate the existing injector on your engine. The part number is typically laser-etched on the side of the injector body, often starting with “0445”. Compare this number exactly to our OE number 0445120219. If the numbers match, it is the correct direct replacement.

Q2: What are the common symptoms of a failing fuel injector that this part will fix?

A: Common signs include engine misfiring (especially at idle), rough running, excessive black smoke from the exhaust, decreased fuel economy, increased engine noise (like a “knocking” sound), and difficulty starting. Replacing a faulty injector with this new unit will resolve these issues.

Q3: Do I need to calibrate or code this injector after installation?

A: While this is a direct mechanical replacement, for optimal performance on modern ECU-controlled engines, we recommend having the injector code (QR code or IMA code) programmed into your engine’s ECU by a qualified technician using diagnostic software. This ensures the engine management system can precisely control the injection timing and quantity for that specific cylinder. If your engine does not support injector coding, the mechanical install is sufficient.
