This strange looking funnel actually works a lot better than it looks. It would take me longer to clean up the mess after doing an oil change than it did to do the oil change. No more oil dripping all over the place from places you can't see. It's definitely a very useful tool to remove your oil filter. They even give you a trick idea on how to remove this filter; one I had never thought of. Guess you'll have to buy one to find out what it is. Ron
This is the first oil filter funnel that woirks on my OEM oil cooler and regular cover equipped Twin Cam 88 Heritage Softail Classic. My only gripe is that there are a lot better tools to punch a hole in the filter than the standard nail supplied by the manufacturer. That's a very small issue compared to the funnel's job of keeping used oil off engine mounts and my garage floor though.
