Assuming it is a first gen CR V, it takes a little work with both the exhaust pipe and the O2 sensor in the way. If you can get enough leverage with a socket wrench you will get it loose. I have done a few after having a 2000 model for 19 years. Good luck.

Also double-check to make sure that the gasket from the filter previously on there does not stay stuck to the block. I had this happen a few years ago and it had two or rings sandwiched together. It went a few miles before it sprang a leak.
