MILIPARTS Aluminum Valve Covers for 3.5L EcoBoost V6 Ford F-150/Expedition/Transit Pair — Left & Right, Direct-Fit Durable Finish

MILIPARTS upgraded aluminum engine valve covers are direct-fit replacements for 3.5L EcoBoost Ford and Lincoln V6 engines, built to improve durability, sealing, and under-hood appearance.

This pair of left and right valve covers from MILIPARTS is engineered as an upgraded alternative to the factory plastic or stamped-steel pieces found on many 3.5L Turbo EcoBoost V6 engines. Finished and machined for a precise fit, the covers are compatible with specific model years of the Ford F-150, Expedition, Transit, Mark LT, and the Lincoln Navigator. They are intended as direct replacements that match OEM mounting points and sealing surfaces while offering the strength and heat-resistance advantages of aluminum construction.

Will these valve covers fit my truck or van?

These MILIPARTS valve covers are designed for particular Ford and Lincoln models equipped with the 3.5L Turbo EcoBoost V6. Confirming your vehicle’s year and engine code before purchase is recommended to guarantee compatibility.

How are these covers better than the stock parts?

MILIPARTS uses upgraded aluminum that improves rigidity and thermal stability compared with many OEM plastic or thin steel covers. The result is a more durable part that resists warping and can help maintain a cleaner, tighter seal under varied operating conditions.

• Aluminum construction reduces heat-related deformation
• Machined surfaces align with factory bolt patterns for a leak-resistant fit
• OEM-quality materials meet or exceed standard durability expectations
• Improved under-hood appearance with a refined finish

What should I expect during installation and maintenance?

These valve covers are made as direct replacements and generally install using the existing bolts and hardware, requiring no cutting or modification. Standard replacement of gaskets and resealing during installation is recommended to ensure a proper, long-lasting seal.

• Direct-fit design uses factory mounting points
• Replace valve cover gaskets and any worn fasteners during install
• Torque bolts to manufacturer specifications to avoid distortion
