Its cast iron construction ensures it withstands high temperatures and resists cracking or warping over time. The round port shape and 1.5-inch collector port diameter maintain proper exhaust gas flow, which is critical for engine performance and emissions control. This manifold does not include an oxygen sensor port, so it is intended for applications where the sensor is located elsewhere in the exhaust system.\u003c\/p\u003e\u003ch2\u003eCommon Applications and Problem Solving\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacement for cracked or leaking exhaust manifolds causing exhaust leaks or noise\u003c\/li\u003e\n\u003cli\u003eRestores proper exhaust flow to improve engine efficiency and reduce emissions\u003c\/li\u003e\n\u003cli\u003eAddresses manifold warping or damage from prolonged heat exposure\u003c\/li\u003e\n\u003cli\u003eEliminates exhaust fumes entering the cabin due to manifold gasket failure\u003c\/li\u003e\n\u003cli\u003eSuitable for restoring factory fit and function on compatible Ford and Lincoln trucks and SUVs\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eEnsure the engine is cool before beginning installation. Remove the old manifold carefully to avoid damaging surrounding components. Clean the mounting surface thoroughly to ensure a proper seal with the included gasket. Torque mounting bolts to manufacturer specifications to prevent leaks. Since this manifold does not have an oxygen sensor port, verify sensor placement in your vehicle’s exhaust system before installation.\u003c\/p\u003e\u003ch2\u003eQuality Assurance and Warranty\u003c\/h2\u003e\u003cp\u003eDorman exhaust manifolds are manufactured to meet or exceed OEM standards for fit, form, and function.
