Designed to replicate the iconic look of the original Volkswagen factory cap but finished in a high-luster, triple-chrome plating, this piece is a staple for any "Cal-Look," show car, or clean daily driver. It provides a seamless transition between vintage aesthetics and custom flair, ensuring your engine doesn''t just run well, but looks the part too. Whether you are running a bone-stock 1600cc dual port or a high-performance stroker engine, this cap fits the standard twist-on oil filler neck perfectly, providing a secure seal that keeps your oil where it belongsinside the engine.

Quality and fitment are paramount when it comes to engine accessories, and this EMPI cap does not disappoint. It comes complete with the necessary internal gaskets to ensure a leak-free experience, preventing that annoying oil mist that can often accumulate around the filler neck. It is designed to work harmoniously with your original factory oil filler or can be paired with an aftermarket chrome oil filler tin for a fully coordinated, mirror-finish look. Don''t settle for a rusty, pitted, or painted original cap when you can upgrade to a durable, corrosion-resistant chrome version that stands out every time you pop the decklid. This is the exact OE-style replacement (Ref Number: 111-115-485) you need to maintain that classic VW silhouette while embracing a custom finish.

PRO TIPS FROM THE SHOP

Tip 1: Inspect Your Filler Neck Tabs

Before installing your new chrome cap, take a moment to inspect the tabs on your oil filler neck. Over decades of use, these tabs can sometimes become slightly flattened or bent. If the cap feels too loose when you twist it on, you can gently use a pair of pliers to slightly adjust the tabs on the filler neck (not the cap) to ensure a tighter seal. A snug fit is vital for preventing oil vapor from escaping, which keeps your engine tin clean and prevents vacuum leaks if you are running a closed-loop breather system.

Tip 2: Maintain the Mirror Shine

Chrome in an engine bay lives in a harsh environment of heat and potential oil spray. To keep your EMPI 4535-20 oil cap looking brand new, we recommend wiping it down with a soft microfiber cloth every time you check your oil. Avoid using abrasive cleaners that can scratch the finish. If you live in a coastal area or a high-humidity climate, a light coating of high-quality wax or a chrome-specific sealant will provide an extra layer of protection against "peppering" or surface rust, ensuring that deep reflection lasts for years.

Tip 3: Don''t Forget the Gasket Seat

When you receive your new cap, ensure the included gasket is seated flat within the underside of the cap before installation. Sometimes during shipping, the gasket can shift. If it isn''t sitting perfectly flush, it won''t create an airtight seal. Also, it is a "pro-builder" trick to apply a tiny drop of clean engine oil to the gasket surface before the very first install; this helps the cap twist on smoothly without binding or tearing the rubber seal, ensuring a perfect seat from day one.
