Angled Oil Filler Extension, With Smooth Cap, Fits VW

OVERVIEW

Upgrade your air-cooled engine''s accessibility and style with the EMPI Angled Oil Filler Extension. Designed specifically for Type 1 and Type 2 upright engines, this premium accessory solves one of the most common headaches for VW owners: the awkward angle and messy process of adding oil to a stock filler. Crafted from high-grade 6061 T-6 billet aluminum and finished with a mirror-like polish, this extension doesn''t just make maintenance easierit transforms your engine bay into a show-ready masterpiece. Whether you are running a stock setup or a high-performance dual-carburetor configuration, the added height and angled orientation provide the necessary clearance to pour oil without a funnel-induced disaster or spilling onto your clean tinware.

Beyond its stunning looks, this oil filler is engineered for maximum functionality and crankcase health. It features a precision-machined 1/4-inch NPT port equipped with a 1/2-inch barbed breather hose fitting, ensuring your engine can breathe properly and maintain optimal internal pressure. The included smooth-top cap isn''t just for show; it features a knurled edge that provides a superior grip, even when your hands are slightly oily, making routine checks a breeze. By threading directly into your existing generator or alternator stand, this EMPI unit offers a rock-solid mounting point that eliminates the leaks and vibrations often associated with inferior chrome-plated steel alternatives. At Appletree Automotive, we recommend this as a "must-have" for any enthusiast looking to combine form and function in their classic Volkswagen.

PRO TIPS

1. Ensure a Perfect Seal at the Base

When installing your new EMPI oil filler, always inspect the condition of the gasket at the base of your generator or alternator stand. While the filler threads in securely, the seal between the stand and the engine case is often a source of annoying leaks. We recommend using a fresh paper gasket with a light smear of high-quality sealant. Additionally, ensure you don''t over-torque the filler into the stand; the aluminum threads are durable, but the stand is often made of softer magnesium or aluminum casting. A firm hand-tightening followed by a slight snug with a wrench is usually sufficient to keep it from vibrating loose.

2. Optimize Your Crankcase Ventilation

The included 1/2-inch barbed fitting is a critical component for your engine''s longevity. Air-cooled VW engines rely on a functional breathing system to prevent pressure build-up, which can blow out main seals or push oil past the piston rings. For the best results, route a high-quality reinforced hose from this filler extension to an oil breather box or directly to the air cleaner on your carburetor. If you are running high RPMs or a large displacement stroker engine, consider upgrading the 1/4-inch NPT fitting to a larger size if you find the engine is still "puking" oil under heavy load.

3. Maintenance and Aesthetic Care

Because this unit is made from polished 6061 T-6 aluminum, it will oxidize over time due to engine heat and environmental exposure. To keep it looking like new, we suggest using a dedicated aluminum polish once or twice a season. Before applying polish, ensure the engine is cool to the touch. When removing the knurled cap for oil changes, always check the internal O-ring for any signs of flattening or cracking. A tiny drop of clean engine oil on the O-ring during installation will help it seat perfectly and prevent the cap from binding, ensuring you can always check your oil levels without a struggle.
