Got a check engine light for your catalytic converter? This is a direct-fit, EPA-approved replacement for a bunch of Ford and Lincoln vehicles from 2013-2019. It fits Ford Explorer, Flex, Taurus Police Interceptor, and Lincoln MKS, MKZ, MKT, and MKX with the 3.5L or 3.7L engines. It's built with a heavy-duty 409L stainless steel shell that resists rust and high heat, and the internal ceramic substrate has plenty of catalysts for a long life. It's made to original specs, so it should bolt right up without modification (though we always recommend professional installation for exhaust work). Important Note: This is a federal EPA-approved part. It is NOT legal for sale or use on vehicles registered in California, New York, Maine, or Colorado. Please check your local and state laws before buying! If you're in a qualifying state and need a reliable, compliant cat, this is a solid choice to get your SUV's performance and emissions back on track.
