RP oil filter?
 

I recently purchased a RP oil filter for a GTR because of the extra length. I know guys are running the purolator pure one filter for the GTR. However, I am concerned that the gasket size is off. Any input would be appreciated.

And you still believe that one size fits all?
On a serious note, if there is enough surface on the engine side (the flat portion on the block where the filter makes a seal) then you should be fine. You see where filter makes contact with the block and still showing a surface area.
