Review on Genuine Honda 30530 PPL A01 Knock Sensor by Payton Luna

I'm glad to confirm that this is a genuine Honda OEM product, complete with the packaging/stamp. I had a P0325 code on my base 2003 Acura RSX 1 month + 400 miles later and the code has not returned since. Of course you can buy the regular one on ebay for $4. But as I suspected after replacing my old one with this one, my gas mileage increased significantly, going from 20-25mpg to at least 24-31 depending on highway use. I am sure that these investments will pay off several times over the years of use.
