Based on the post I've been reading, this question is probably for Greg. Just curious as to why the filter element in the V4 intake by EC doesn't need to be oiled like other cotton mesh filters. If it doesn't require oiling, would oiling it reduce airflow considerably? I want to trap as many particles as possible. I also want to keep my engine warrant valid. My V4 should arrive this week with an oil catch can to follow. Please advise.
