i want to put a cold air intake and a flow master in.
any good brand anyone knows i shoud get?
and even anything else i should do to it
without losing the warranty?

The AEM intake is the one that scion let's you add as an add-on. I, however, like to go with Injen. You can go with cold air or short ram... i've heard there are some flooding issues with the cold air, so short ram does the job there - suppose it really just matters where you live. On the other hand, longer barrel means more hp.

As for other mods - I talked to my dealer about mods and the warranty; he told me that as long as I get 'certain' aftermarket mods installed by a professional/shop then my warranty should still be active. Doesnt sound right to me, but I'm pretty much set to forego my warranty for the mods.

So if you want to mod, be prepared to lose that warranty.

thats total bull ragga dont listen to Z ....look at my post on some mod and warranty info....its good stuff, the fact of the matter is that dealers want your money and if they have to screw you over to get it they will....heres the link>>>>http://www.scionlife.com/forums/viewtopic.php?t=132438

Sorry for being so harsh Z, i just wanted to make sure you dont scare noone out of knowing their Rights......

AEM has a bypass valve available if you buy a CAI. It would prevent any flooding worries...........

LOL, funny I saw this post. I have an AEM bypass installed on my CAI and is just redoing my engine compartment and noticed th bypass filter had a little tear in it and was looking to see if any had a good fix for it :)

btw. I like a PW Box.
