OEM Type-S oil pump part #15100-PRB-A01 and Acura RSX Windage Tray OEM Part #11211-PNC-000 are both required.

K20A3 flywheel inspection cover #21351-PNA-000 + bolts (x3) #95701-06012-08 are highly suggested for RSX Type-S and JDM K20A engines when using this oil pan (K20A/A2/Z1 inspection cover will become incompatible). K20A3 shorter oil pan bolts are also required #95701-06016-08 (x16).

* A Type-S oil pump may require slight notching to clear certain K-series main caps. Please do your research for a K-series Type-S PRB oil pump upgrade before purchasing this pan.
