I see alot of people asking what performance modifications will do to their warranty or that they are going to wait until the warranty expires before taking any of the stock parts off. The dealer isn't supposed to deny warranty coverage unless something you do actually causes the problem. This is covered under the Magnuson Moss Warranty Act -
US Code - Title 15, Chapter 50, Sections 2301-2312
Legally, a vehicle manufacturer cannot void the warranty on a vehicle due to an aftermarket part unless they can prove that the aftermarket part caused or contributed to the failure in the vehicle (per the Magnuson Moss Warranty Act (15 U.S.C. 2302(C)) . For best results, consider working with performance-oriented dealerships with a proven history of working with customers. If your vehicle manufacturer fails to honor emission/warranty claims, contact EPA at (202) 260-2080 or www.epa.gov. If federal warranty protection is denied, contact the FTC at (202) 326-3128 or www.ftc.gov. For additional information, check out the following links:

Some dealership service departments are easier to work with than others. I've talked to customers that had dealers that were happy to see performance mods on the car while there are others that don't like to see the filter changed. But when it comes down to it, they can't say anything about it. On the other hand, if you bring the car with rods hanging out of the block and a nitrous bottle in the trunk, that will probably put up a red flag right from the start
