603 Oil Guage High after Oil Change

[86-300sdl]

Normally after I do an oil change my 603 the oil gauge sits around 2 on the gauge at idle and pegs under throttle.

Now it's sitting close to the 3 at idle well after warm up.

Could this be telling me my aftermarket oil filter may be messed up and not allowing pressure to drop at idle? I'm not sure where the filter sits in regards to oil return journals and oil pressure sensor.

Same oil as always, weather the same, etc, etc
