Question 2: What thread does your filter have?
Now measure the outer diameter of your thread on the filter!
And compare your thread with the images below to see if you have a coarse thread or fine thread!
Please simply measure the diameter outside. This must match the specifications below within plus/minus 2 millimeters. The inner diameter of the hole is irrelevant. Compare with the images below of the old filter thread.

1 1/2 inch COARSE THREAD approximately 46mm diameter
to the EGO3 Filter 2 -
