Informer your an idiot. OK, for the last time, if you put a CAI on and your engine blows up, your warranty will fix it. If you put a CAI on and you go through a small stream and suck water into your engine, your warranty will not cover it. The aftermarket part HAS to cause the problem for it to not be covered by your warranty. If they won't fix it cause you have an aftermarket part on then hire you a lawyer and take them to court, they WILL lose, but any decent dealer will not say s*** about an exhaust or an intake or anything.
So to recap, stay with me here Informer. Intakes, exhaust, plug wires, springs, rims, tires, pulleys, non of that will void your warranty, just use some common sense. Nitrous, turbos, OK if your engine blows then they prolly won't fix it if they see the nitrous or turbo, just take it off when you take it to the dealer.
And if you say different Informer you are the one full of s***. I had tons of mods on my 2000 Eclipse and they never said anything at the dealership, and I have researched this topic alot.
With a name like Informer you should actually know some s*** before you post.
