Angled Oil Filler Extension, With Grooved Cap, Fits VW

OVERVIEW

Upgrade your air-cooled engine''s functionality and aesthetics with the EMPI Angled Oil Filler Extension. Designed specifically for the classic Volkswagen enthusiast, this premium component solves one of the most common frustrations in the engine bay: the cramped and messy process of adding oil. On many Type 1 and Type 2 engines, especially those equipped with larger aftermarket carburetors or dual-carburetor setups, the stock oil filler location can be nearly impossible to reach without a long funnel and a steady hand. This extension threads directly into your existing generator or alternator stand, angling the fill point upward and outward to provide a clear, unobstructed path for pouring. Beyond its utility, the brilliant, fully polished finish serves as a striking focal point, cleaning up the look of your engine while providing a professional, custom-show appearance that lasts for years.

Precision-engineered from high-quality 6061 T-6 billet aluminum, this oil filler extension is built to withstand the high-heat environment of a performance VW engine without warping or leaking. It features an integrated 1/4 inch NPT to 1/2 inch barbed breather hose fitting, which is essential for proper crankcase ventilation to prevent oil leaks and pressure buildup. The included billet aluminum cap is meticulously grooved, ensuring a non-slip grip even if your hands are oily, making routine maintenance faster and more efficient. Whether you are finishing a ground-up restoration, building a high-performance street sleeper, or maintaining a rugged off-road sand rail, this EMPI extension is a "must-have" upgrade that combines rugged durability with the classic "California Look" style that Appletree Auto customers demand.

PRO TIPS

Tip 1: Ensure a Leak-Free Seal

When installing your new EMPI oil filler extension, always inspect the threads on your generator or alternator stand first. Old stands often have debris or slight burrs that can prevent the aluminum threads from seating perfectly. We highly recommend using a small amount of thread sealant or a fresh gasket at the base to ensure a liquid-tight seal. Since you are working with aluminum, be careful not to over-torque the unit; a snug fit is all that is required to prevent vibration from loosening the cap or the body. If you are switching from an old-style press-in filler to this threaded version, ensure you have the correct threaded stand installed on your engine block.

Tip 2: Optimize Your Crankcase Ventilation

The 1/2 inch barbed fitting included with this extension is a critical component of your engine''s health. Air-cooled VW engines rely on a functional breather system to relieve internal crankcase pressure. For the best performance, route a high-quality reinforced hose from this barb to either your air cleaner (if using a stock-style or certain aftermarket carbs) or, better yet, to a dedicated oil breather box. This prevents oil mist from coating your engine bay and helps your piston rings seal more effectively by maintaining proper pressure differentials. Check this hose periodically for cracks or clogs to keep your engine running clean.

Tip 3: Clearance for Dual Carburetor Linkages

If you are running a dual-carb setup, such as Weber IDFs or Dellorto DRLAs, linkage clearance can be tight. Before fully tightening the filler extension, do a "dry fit" with your throttle linkage at full wide-open throttle (WOT). The beauty of this angled design is that it can often be clocked slightly to clear crossbar linkages or air filter housings. Having that extra inch of clearance can be the difference between a smooth throttle response and a sticking linkage. If you find the fit is tight, you can often use thin shims or spacers to adjust the final resting angle of the filler neck to perfectly suit your specific carburetor configuration.
