Denso is a product supplier for Toyota--
I highly doubt your dealer went to the trouble of putting a non-oem part in an oem package.

Right. I probably just didn't word my question correctly the first time... Denso is the OEM supplier of the knock sensors for our trucks. However, the knock sensors I got from my local dealer don't have the "Denso" logo on them like I have seen in other pictures of the part. This makes me concerned that I got a non-OEM part, and I wanted to verify if possible.
Call them up and have a friendly chat. It may be a superseding part/company , or wait for Beno or the like to chime in--

I mean, I totally agree... but you can see yourself from the pictures that they look like different parts. So, it kind of leaves a person to wonder...

Two of the take offs sitting here have that marking, possibly original? That said, Toyota, in their race to become GM, who knows where the stuff comes from anymore?
Toyota Camry Corolla 4Runner Previa Sienna Tacoma Avalon Knock Sensor B882
According to the "description" at the bottom of the listing it is not OEM.

That is an OE part from Matsushita.
Denso isn't the ONLY manufacturer of knock sensors for Toyota.

Oh okay. Thanks for that, I appreciate it! I thought Denso was the only OEM manufacturer of knock sensors for our particular trucks - they're the only ones I'd seen while searching mud. Searching google confirms Matsushita is also a supplier for Toyota.
The guy who works for Toyota also confirms they are a supplier for Toyota... 
A knock sensor is basically a very dumb version of an accelerometer. When detonation(knock) happens, a small piezoelectric crystal sends a signal to the ECU and the ECU adjusts the spark timing, fuel delivery, etc to prevent further knock.
An accelerometer could accomplish the same thing, but would require extra electronics to filter and watch for an impulse from detonation. While this is a much "smarter" way to accomplish the same task, it is more expensive/complex and more expensive than a dummy-proof piezoelectric sensor.

Interesting conspiracy, but I don't have anything to do with bagging parts.
FWIW, That sensor is linked to LC70/80/100, Crown, and Dyna
