This is a very touchy subject actually. Like if you buy a CAI your factory rubber intake, black box & bong, IAT sensor, and all that will become void when you put that in. If you lower your car for say coil overs or progressive springs on OEM struts or even aftermarket struts. Your strut mounts, OEM struts and what have will all become void. If you run N20 on your car they will void the whole thing right then and there. Basically stay away from hardcore engine mods ( i.e. forged pistons and rods ) or even more agressive cams. Motor mounts are ok. But really what it comes down to is the dealership discresion and has to be proven that the problem that went wrong was caused by infact the aftermarket product. There was a bill passed called the Magnussion Moss or somthing like that that state they can't void your warrenty unless it's proven that mod broke it.
