If you’re running a CAT C15 Acert (2008–2010), upgrading to a PDI Big Boss Billet Aluminum Oil Fill Cap is a simple way to eliminate the problems that come with weak factory plastic caps.
Many OEM oil fill caps are made from plastic, which can crack, loosen, or start leaking over time due to constant engine vibration and heat. In some cases, low-quality caps have even been known to work loose and fall off while driving, leaving a mess in the engine bay and creating bigger problems down the road.
The PDI Big Boss Oil Fill Cap is machined from solid high-grade billet aluminum, making it far stronger and more durable than stock plastic caps. The upgraded design provides a more secure fit and improved reliability under heavy-duty engine conditions.
Note: These oil fill caps are now a threaded design rather than the previous lock-tight style, providing a secure and dependable seal.
This upgrade helps keep your engine bay cleaner, better sealed, and looking sharp while providing long-lasting durability.
