Ignition Knock Sensors

This knock sensor did the trick! Engine's smooth now.

I was excited to get this knock sensor installed on my 2006 Honda S2000. The knocking sound was pretty annoying, and I hoped this would fix it right away. It did work eventually, but it took a couple of days for the knocking to stop completely. I guess it needed some time to adjust or something. So if you get this, be patient, it does work.
