I bought a Universal Oil relocation kit with the Oil Cooler for my S.The F series motor has a stock oil cooler on it, so I removed it but the thread is 22mm on the block and the oil filter is 20mm so what I did ,I went to the dealer and got the 22mm to 20mm nipple out of a 1.8L 06 civic I don't have the part number on me, but whoever need it, you can just tell them it's the oil filter adapter ( the one spin on between the oil pan and the filter) , it is thread one end 22mm and the other end is 20mm
hope that help and save you the trouble finding it. good luck
