I've been using it for a few months now and it was very easy to install. You don't have to be a rocket scientist, you just need to know what you're doing or be able to follow instructions from YouTube videos. The only reason I bought it was just for a hobby, but surprisingly my car runs a little better and I think it's due to the better airflow of this filter compared to the standard air filter that came with my car. came in a retail box with various sized adapters (my car needed 3" or 3.5") and there's not much more to say than it fits with no problems.
