That looks the same, but the wording is a little weird when it calls out non-metric Honda. This is the one I bought that I know works. I wasn't sure on the approved vendor list or link rules here yet. Here's the one I boughtNo worries. Im guessing its this one?

Well, sadly the part does NOT fit, and you do need to take a grinder to the oil filter housing.To be clear, the correct part for a 2013 Honda Civic Si is a M20-1.5.

Not only does the Prosport oil filter adaptor plate NOT fit with the lip on the oil filter housing, the part itself needed to be ground down a few millimeters. I spent hours grinding and checking fitment, but all is well that ends well.

The pictures above are after a fair bit of grinding, but even more was needed. I used an angle grinder and followed it up with a dremel to clean things up. The entire outer ring of the oil filter sandwich had to be removed, but be careful not to cut into the inner rings. The entire lip on the oil filter housing also had to be removed. I also put some duct tape over the oil filter housing to keep debris out.
Anyway, it sealed up fine. No leaks (fingers crossed). If you plan to do this, be careful and plan to spend a few hours on something that should take 15 minutes.
