The short answer is: you’re protected by the Magnuson-Moss Warranty Act, so a dealer can’t void your warranty just for installing the Sinister Diesel Fuel Filter Conversion Kit on your 2011-2025 Ford Powerstroke 6.7L—unless they can prove the kit caused the issue. Our kits are engineered to be fully compatible with your truck’s factory systems, and thousands of customers have used them without any warranty problems. However, since warranty decisions are ultimately up to the dealer, we always recommend discussing any concerns with your service advisor before making modifications.
