Review on Simplify engine maintenance 🔌 with Beck Arnley BEC039-6558 Semi-Circular Plug by Mike Kies

My wife's Honda Civic leaks where the thing clogged the engine. I'm not sure why Honda added these plugs (not sure what they think of many of their design flaws), but they always start to fail after a few thousand miles. It was already starting to pop out of the side of the motor and fall apart when I took it off. After cleaning the hole as best I could, I put in a new one. It seems like it's doing its job. I have no idea why Honda put a hole there.
