YUNDA 30530-PNA-003 30530-PPL-A01 1580917 5S2320 KS197 Engine Knock Sensor for Honda Accord Civic CR-V Element,Acura-RDX RSX TSX 158-0917

Got this from amazon, It came in original box and wrapped in plastic, the plastic was stretched and was a little dirty from a garage. I put some on my truck two months ago and they're without a doubt the best product I've installed. My f150 got these and I honestly wouldn't buy anything else. Please keep in mind I'm aware there's better products available at much higher prices but I'm not a race driver on a closed course, neither is half the folks who run them but that's their money, but for my money I refuse to buy cheap off name brand junk, and draw the line at really high priced stuff that earned their reputation from spending money advertising rather than research, I usually go with mid priced stuff such as these and I found a real gem with these, I'd definitely recommend this to someone!

My CEL light was on in my 04 Honda CRV and the code scanner indicated a faulty knock sensor. This part actually made the engine run worse than the failing OEM part. CEL came back on after it was installed. Engine lugged horribly uphill and under accelleration. Bought the $67 genuine Honda part and the problems were fixed. Replacing this part is a little tricky if you don't want to pull the radiator and exhaust manifold so you only want to do it once.

Great product

Part worked well for a week and then died. Had to go get a new knock sensor from Honda

Always replace this sensor if you're replacing your starter
