<h3>Key features</h3><ul> <li>Excellent Sealing: The engine cylinder head gasket utilizes a multi-layer steel (MLS) structure and a fire ring design to effectively seal the combustion chamber, preventing high-temperature, high-pressure gas leakage. It also prevents oil and coolant crosstalk, resolving common engine problems such as white smoke, oil emulsification, and coolant intrusion</li> <li>High-Temperature and High-Pressure Resistance: The cylinder head gasket is made of a high-strength metal composite material to withstand extreme operating environments (high temperature, high pressure, and vibration), resisting aging and maintaining stability. Long-term stable operation significantly extends engine life and ensures optimal power output</li> <li>Widely Compatible: Cylinder head gaskets fit Ford Expedition Explorer, F150, F250, and F-350 4.6L and 5.4L engines, as well as Lincoln Navigator and Mercury Mountaineer models from 2004 to 2014. Please refer to the detailed instructions for compatible models. Replaces 26306PT and 26307PT, ensuring precise installation of both left and right cylinder head gaskets without modification</li> <li>Improve Engine Efficiency: Cylinder head gaskets effectively address issues such as power loss, starting difficulties, odor, and oil and water leaks caused by aging. Replacement restores the cylinder compression ratio and restores your vehicle to peak condition</li> <li>Easy Installation: Each cylinder head gasket kit includes both left and right cylinder head gaskets, allowing for a more thorough, one-time replacement. The optimized surface coating ensures a seamless fit between the cylinder block and cylinder head, and a clean, flat mounting surface ensures a reliable seal</li> </ul><p>Free shipping included. 30-day hassle-free returns.</p>
