No. According to the Magnuson-Moss Warranty Improvement Act, dealers or salesman cannot legally void your warranty simply because you failed to use the original equipment part. They must prove how the product actually caused a problem. Therefore, using aftermarket high performance products such as cold air intakes and high performance spark plugs will not affect your warranty.
