Q: Are the carbon deflectors covered by a warranty?

They carry a 5-year structural warranty covering fitment and functionality for the original owner. That structural coverage is separate from cosmetics: because the parts arrive as a base coat meant to be clear-coated or PPF-protected, the warranty does not cover visual issues like UV fading, discoloration, scratches, or rock chips on unprotected parts. Protecting the finish soon after install is the way to keep them looking right long term.
