The filter fit well and looked to be well-constructed. Felt and sounded like some improvement in engine performance and sound. I'll need to avoid over-oiling it whenever I clean it...which should be a long time from now. Only drawback might be less efficiency than a paper filter, thus engine oil get dirty more quickly.
