Upgrade the engine bay of your 2011-2025 Ford Super Duty with the Wehrli WCF100288 Billet Aluminum Oil Fill Cap. Designed for trucks equipped with the 6.7L Power Stroke diesel engine, this clear anodized cap is a complete replacement for the factory plastic oil fill cap—not merely a decorative cover. It provides a clean, durable appearance while maintaining the fit and function of the original component.
The Wehrli oil fill cap is CNC machined from billet aluminum in the USA and engineered with a machined cam-lock engagement for secure installation. An included O-ring seal helps provide a dependable seal at the filler neck, while the direct OEM replacement design allows the cap to install in seconds using the factory mounting location. The engraved Wehrli Custom logo on the bottom adds a subtle brand detail without distracting from the clean finish.
This clear anodized oil fill cap complements Wehrli billet aluminum coolant tank and brake reservoir caps for a coordinated engine-bay appearance. It is an ideal replacement for the original plastic component on 2011-2025 Ford F-250 and F-350 Super Duty trucks equipped with the 6.7L Power Stroke engine. The Wehrli WCF100288 combines durable construction, straightforward installation, and factory-style fitment for a practical engine-bay upgrade.
