Resolved my check engine light.
Awesome fit. States it didnโt fit my vehicle but after some research, I found that it would. I installed them and after a test drive, no codes returned and it resolved my problem. Much cheaper than the OE and after a week seems to be the same performance as well. Would recommend this kit for a dealer alternative. The comparability for these sensors is very wide for Toyotas.

Cheap knock offs
Don't follow torque specs on these. I broke one off in the cylinder head. Fortunately I was able to extract it. Good price though. One sensor at the parts store was 83 bucks! Update, these are cheap knock offs. just buy Denso Toyota brand ones and be done with it. The cost of time and parts to tear the top end off a second time is more expensive!

Great product!
Used this to trick the computer in my Toyota Sienna into thinking that the original knock sensor was working properly. By mounting it somewhere stable and bypassing the one in the block it worked like a charm. Dorman products are top notch.

Fits just right 2001 Solara
Its a big job to do, But these sensors threaded in nicely, Dorman products usually play well with Toyota fitment. The Price for these were off the charts great for what you getting. I will know more once I drive the vehicle and turn off the check engine light.

Thumbs up
Installed on 02 es300 work car with 340k miles a while back. So far so good. Before I changed them, the car wouldnt run right. It had no power and wouldnt go into O/D. I cleared the code when I replaced them and problems solved.

Works so far
This installation took me very very very long. I ended up getting a set of gaskets, an angled ratchet for those stubborn bolts behind the plenum. I also did the spark plugs and ignition coils, half are buried under the plenum. Save yourself some money and buy them from RockAuto if you are in Canada, amazing prices, fast shipping. Also, get some coolant or drain it beforehand because it'll need replacing. Overall, hoping that these things last. Will update if anything changes.

Connectors would not fit
Once again I thought I could cheap out and buy this quick change kit but it ended up causing more issues! Unsure why whether it be bad sensors or wording harness was wired wrong, the 4 pin connecter would not click in properly so I had to zip tie it and after installing had huge loss of power and went from 1 code too 2 bad knock sensor codes aka DO NOT BUY!!!

Works, sort of
One sensor broke as I was tightening it. The harness to vehicle connector needed to be swapped with the original. Does not plug in as is. Harness did resolve knock errors after extra effort
