I think mopar is under warrantyOriginally posted by 03WRX
You are correct. Copied from the Mopar website:
HOW DOES THE INSTALLATION OF THIS KIT AFFECT THE VEHICLE'S WARRANTY?
Performance or racing parts are considered to be non-DaimlerChrysler parts. Repairs or adjustments caused or required as a result of their use are not covered under your vehicle's factory warranties. This information can be found in the Warranty Information booklet in the glove box of each new vehicle. Refer to Section 3. What's Not Covered.
