So there’s two options when buying the oil filter 2.52 and 3.23 .. which one do I get?

 

What are those numbers in reference to?

The SKU you would want is 04152-31110.

 

So when I look up this is what I get

 

That is strange... I'd almost be willing to bet the measurement is the size of the box it comes in, not the filter, as the filter should not change size depending.

If it were me I'd get some clarification from RP themselves.

 

Just stick with OEM, there is no reason to choose aftermarket when the OEM filter is already so good.
