MLS Exhaust Gasket - Ford 4.6L SOHC

The COMETIC GASKETS MLS Exhaust Gasket for Ford 4.6L SOHC engines is a multi-layer steel manifold gasket designed to seal the junction between the cylinder head and exhaust manifold on Ford modular engine platforms. This gasket is engineered to handle the thermal cycling and pressure loads inherent in exhaust gas flow while maintaining a reliable seal across repeated heat cycles—a critical requirement for vehicles running stock port configurations where OEM gaskets frequently fail under sustained use.

Multi-layer steel construction provides superior sealing surface compared to standard composite gaskets, resisting blowout even when manifold warping occurs from high exhaust temperatures. The gasket comes as a pair, covering both driver and passenger side manifolds typical of the 4.6L SOHC configuration. Cometic is recognized in the performance and restoration market for precision gasket engineering; MLS (Multi-Layer Steel) designs are industry standard for applications where thermal stress and reusability matter. Installation requires standard manifold fastener torque procedures; no special tools or techniques are needed.

This replacement is essential for Ford owners addressing exhaust manifold leaks—whether after removing and reinstalling headers for valve cover work, spark plug access, or full manifold replacement. It's equally applicable to restoration work on Fox-body Mustangs, 2004–2008 F-150s, and other platforms using the 4.6L modular engine. The part number C5853-030 ensures fitment to stock port specifications without requiring porting or port matching.
