I blame Harley-Davidson for even needing this. A silly placement of the oil filter requires a funnel (I've used a cut bottle in the past). Not entirely flawless yet, but pretty good. Again, the silly design and lack of a proper fill hole for the main body make the shallow funnel a must-have. There's still some leakage, but it's better than none. The O-rings are a nice addition, but the nail seems pointless: I threw it in the trash.
