This modification along with any other modification done to your vehicle "can possibly" void your warranty. In order to void the warranty, this modification would have to be the cause of the issue though and the dealership would have to prove this modification voided your warranty.

You may look into them installing the intake for you, that may ease any concerns on their part.
