ok guys our direct injectors, if you look at lexuspartsnow.com shows you for example 23209-39155-B0, that is for "mark black" but they also list as being compatible, mark brown mark yellow etc.... what exactly does this mean?
1. Why is there this difference?
2. I assume I cannot mix and match?
3. But can I for example swap all my mark black for mark browns?
4. I read that different colours are different flow rates?
5. And also i was told that 23250-31020 and 23209-39055 are interchangeable with 23209-39155 how doI find out more about this?
I need some definitive information before I purchase.
