FAQ

Q1: How do I verify that this spacer (7169-685) fits my engine?

A: The most reliable method is to compare the OEM number (7169-685 or 7169685) with the part number stamped on your existing injector spacer or listed in your engine’s service manual. As this is a generic part used in many common rail systems, confirming the OEM number is the best way to ensure a correct fit.

Q2: What is the purpose of this injector spacer in a common rail system?

A: This spacer is used to set the correct protrusion height of the fuel injector nozzle into the combustion chamber. Proper height is critical for achieving the correct spray pattern, compression ratio, and sealing pressure. An incorrect or worn spacer can lead to poor combustion, increased emissions, or injector failure.

Q3: What is the minimum order quantity (MOQ) and how is the part packaged?

A: The standard minimum order quantity (MOQ) is 50 pieces. We can accommodate custom packaging based on your request. For smaller trial orders, please contact our sales team to discuss options. Each single item is packaged in a compact box (4x3x2 cm) to ensure safe transit.
