yeah they can be.. thats jsut what i suggest man.. this way the car is out of warranty, and when it comes down to it if you tell you mom you wanna mod it and its out of warranty she wont car as much cuz lets say you through intake and a boost controller on it, and something weird happens not neccesarily something you caused maybe there was a defect in the car before hand... then you warranty is gone and your out almost 5k to get a new motor.. see what im saying? if there's a defect in the motor surely it will come out in that 36,000 miles.. thats why i highly suggest not modding the engine until thats over with.. i wish i had waited but im also not under mom and dad's wing the car is in my name and im free to do as i wish to it.. if you do want to mod the car pls consult it and the possibilities of what it can do and how your mom would feel about having to pay for a car that doens't run if something does happen.. dont think about it strickly form ur point of view but form the point of view of those it affects.
