I'm sorry but, I fail to see in your link where is says a non TRD part can void a warranty.
Fist off, that woul be illegal (at least in the US) unless Toyota can prove that it caused a particular problem that you claim is a warranty issue.
The same would be true for any after market part.

As far as a K&N filter, since Toyota also sells the exact same kind of filter, they can't legally claim it caused a problem.
