Air Cleaner Element, 4.5 x 7 x 3.5 Tall, Oval, Gauze

OVERVIEW

When it is time to refresh your engine''s intake system, the EMPI high-flow gauze air cleaner element is the professional''s choice for maintaining peak volumetric efficiency. Designed specifically for the iconic oval-style chrome air cleaner assemblies found on thousands of air-cooled Volkswagens, this 3.5-inch tall element provides a significant increase in surface area compared to shorter stock-style filters. This extra height allows for a greater volume of air to reach your carburetor, which is essential for modified engines or those running Weber Progressive series carburetors. In the world of air-cooled engines, heat and debris are your primary enemies; by utilizing a high-quality gauze filtration media, you ensure that microscopic particulates are trapped before they can scar your cylinder walls, while still maintaining the high-velocity airflow required for crisp throttle response and maximum horsepower.

At Appletree Automotive, we know that many enthusiasts overlook the importance of a clean filter until performance begins to stumble. This EMPI replacement element is not just a standard paper filter; it features a robust gauze construction that is designed to be washable and reusable, providing long-term value and consistent performance in both street and off-road environments. Whether you are cruising in a classic Beetle or tearing up the dunes in a high-performance sand rail, the oval 4.5 x 7-inch footprint fits perfectly into your existing EMPI or similar aftermarket housings. Replacing a clogged or oil-soaked filter with this fresh gauze element will immediately improve your engine''s ability to breathe, ensuring that your air-fuel ratios remain stable and your VW continues to run cool and reliable for miles to come.

PRO TIPS

1. Avoid Over-Oiling Your Gauze Element

When you clean and re-oil this gauze element, the most common mistake is applying too much filter oil. If the filter is dripping or saturated to the point where the oil begins to migrate, it can actually be sucked into the carburetor air jets or onto the venturis, causing a stumble or a rich-running condition. Always apply the oil evenly, let it sit for 20 minutes to "wick" through the fibers, and then use a clean shop towel to dab off any excess from the rubber seals before reinstalling it onto your engine. A properly oiled filter should look consistent in color but should not feel "wet" to the touch.

2. Verify Decklid and Hood Clearance

This element is 3.5 inches tall, which is significantly taller than the standard 2-inch or 2.5-inch versions often found in kits. While the extra height is fantastic for airflow, it can create clearance issues in tight engine bays. Before slamming your decklid or hood shut, we recommend placing a small ball of aluminum foil or "Plastigage" on top of the air cleaner housing and gently closing the lid. If the foil is crushed flat, you may need to use a shorter element or a "drop-base" air cleaner assembly to avoid damaging your paint or the air cleaner itself. This is especially critical on Karmann Ghias and Type 3s where engine bay height is very limited.

3. Off-Road Maintenance Cycles

If you are running your VW in a dusty environment like a desert or a dirt track, don''t rely on a visual inspection alone. Fine silt and "bull dust" can clog the pores of a gauze filter long before it looks physically dirty. For off-roaders, we recommend carrying a spare pre-oiled element in a sealed plastic bag. When you notice a drop in top-end RPM or a slight change in your idle quality, swap the filter out immediately. Cleaning these filters is easy, but doing it in the field is messy; having a fresh one ready to go ensures you spend more time driving and less time cleaning while on the trail.
