Yeah like the title said, Im about to buy gas cap.

Right here local autoparts store, they offer me plastic and metal gas cap.
I dont know what or which better??

Or i guess both performed samething right? It just cap, no biggie.

Factory is plastic. I would be careful with non-OEM as you may then have leaks (vapor out or water in); both of which are not good.

As stated above, go OEM. They are not that expensive from C-Dan. If a cheap one leaks vapor, which my 10+ year old OEM did, you can end up blowing up your garage.

I'd get one from Toyota. There are a couple important features in that little cap that can cause problems - they're more complex than you think.

Two years ago I had to buy from to pass smog so they slapped a Fram one on, I believe, for $9.
Stupid part was that I couldn't leave and get a factory cap or I would have to do the test all over again. Good Old Republic of Kalifornia.
Anyway, the Fram one looks the same as the OEM one IMO and has worked fine.
