FAQ

Q1: How can I confirm that this 0 433 271 517 nozzle will fit my engine?

First, check the part number printed on your existing injector nozzle. It should match 0433271517, DLLA140P517, or 0 433 271 517. If the numbers match, it is a direct replacement. If you are unsure, please contact us with your engine model and the current part number for verification.

Q2: What is the difference between a “DLLA” nozzle and other types?

The “DLLA” designation refers to a specific Bosch nozzle design, which is a multi-hole, long stem nozzle used in modern direct injection diesel engines. The “140” in DLLA140P517 indicates the spray angle (140 degrees), which is critical for matching the combustion chamber design. Using the correct nozzle type like the DLLA140P517 ensures proper fuel atomization and engine performance.

Q3: What is the minimum order quantity (MOQ) and how should I store these nozzles?

The MOQ for this item is 48 pieces. For storage, keep the nozzles in their original packaging in a clean, dry environment to prevent contamination or damage. They should be handled with care to avoid damaging the precision-machined tip before installation.
