I recently purchased a 2013 Hyundai Elantra limited sedan and I love her, but I want her to be faster off the line. my car is covered fully under warranty and I don't want to do any work that will negate that warranty. I was looking at some performance air intakes. I was also told about some performance chips, but I have only see bad reviews on those and don't know if there are working ones for the 2013 model yet. Any help would be appreciated. I will admit that I am new to this, so please forgive my noobiness...lol.
