When building the K24Z motors like the 9th Gen Civic Si and TSX to turn out big power and 8000+ rpms the factory oiling system becomes inefficient and problematic due to the balance shafts the OEM oil pump uses. The most common and cost-effective solution to this is swapping in the Acura RSX Type-S PRB oil pump to eliminate the balance shafts and better supply oil.
This piece is required to properly triangulate the PRB oil pump and install the windage tray properly without have to haphazardly modify for fitment.
