I wanted to know if all B series oil jets are the same? The reason why i ask is because Honda sells their oil jets from a 99 Civic Si (B16) for $12 while Acura sell theirs at $25 per piece. I am rebuilding my 97 Acura Integra GSR block so I would like to know. They also share common part number. Civic Si oil jet part number is 15280-PR3-000 while Acura GSR oil jet part number is 15280-P72-000. So does that make a differences?

 

I have taken apart a lot of b series and never really noticed if one was turned the other way, i would just buy one of each and take back the one that is the most expensive if the are both ther same
