南非采购需求：机械发动机零件

Hello! I'm looking for injectors sleeves for a specific engine model that I need to procure. Could you share the availability and pricing for these parts? Additionally, it would be great if you could provide information about the materials used and whether there are different options or variations available. I'm also interested in the lead time for production and shipping, as well as any minimum order quantity requirements you might have. If you could send along any relevant technical specifications or catalog data for your offerings, that would be super helpful. Looking forward to your prompt response—thanks!
