since I had well over 12 months/ 12k miles left on the Celica's warranty it piggy backed on that.
Othewise, I would only get 12 months/12k miles if i installed it myself.

They don't give you less warrany it you install it yourself. They give you more warranty if the dealer installs it providing you still have warranty (over 12 months/12k miles) left on the car to begin with.

This has been standard warranty practice for TRD parts for years.

The difference in warranty coverage is dependant on who installed the TRD part; authorized dealer installed, no issues with part or vehicle warranty, but as my TRD link stated, non-authorized installer of TRD part can void warranty of part, or vehicle, or both.
