As a former car dealer and present aftermarket dealer... Here's how it works:
The warranty on your car is not effected unless you make changes to the stock components... and then only those pieces are voided from the warranty.
Example: If you remove your factory h/u to replace with a Pioneer... Your audio system is now void under warranty.
If you remove your stock alternator to put on a high output alt... Your charging system is now void under warranty
If you remove your intake to put on a cold air... You got it!... Your intake system is now void under warranty.
I think you get the idea

Your best bet is to get your new system from an authorized dealer so it will be under the aftermarket companies warranty :)
