This question has no hard and fast answer...dealers will be suspicious if you show up at their service department driving a highly modified SRT and complaining about defects. Like I said, adding performance parts does not void your entire warranty. If there is an issue, technically the burden is on the dealer to prove that the particular part caused the problem. There is a myth that Mopar Performance Parts will not affect warranty coverage. This is FALSE. As far as Chrysler is concerned, Mopar Performance is just like any other aftermarket supplier. The "Mother Parts" catalog carries a disclaimer stating the following..."Competition parts are sold 'as is' without any warranty whatsoever...Chrysler Co. vehicle and parts warranties are voided if the vehicle is used for competition OR IF THEY FAIL AS A RESULT OF MODIFICATION." Installing a Mopar Performance part qualifies as a modification to the original car. In fact, until the 2000 catalog came out, MP parts themselves were not even warranted against defects. While they still void the car's warranty, most defective parts are now covered...
