Changed my plugs after 38k (PICS)

Dude they have not been a part of toyota for 62 years >> http://www.globaldenso.com/en/aboutd...ory/index.html Denso and NGK both bid on contracts to supply all automakers with their product from the factory. Denso happened to win the yaris contract. Nothing to do with ownership but rather dollars and cents. Denso and NGk also private label their products for toyota and numerous other auto companies. That is why if you buy from the dealer some will have denso on the plug but a different part # which is usually the toyota part #. Denso will also assign a different part # to signify that it is a toyota private label plug.

Wonder how the difference would be noticed if at all on a boosted motor...

The difference is whether or not you're going to have misfires under load. Gap is very important on an NA to FI engine. You can't just run the same gap spark plug.

Yes, they are an independent company and they must bid for Toyota contracts just like NGK, etc.
However, as I understand it, Toyota owns a large portion of Denso stock so, yes, Toyota owns part of Denso.

What are the torque values for the plugs?
