Air Cleaner, for IDA, 5.5 X 9 In Oval, 3 In Tall, Gauze

OVERVIEW

When you are running a high-performance air-cooled engine equipped with Weber IDA carburetors, you know that airflow is the lifeblood of your horsepower. This EMPI 5.5 x 9-inch oval air cleaner is the definitive solution for enthusiasts who refuse to compromise between engine protection and raw performance. Designed specifically to bridge the gap between high-volume induction and the tight constraints of a Volkswagen engine bay, this assembly features a 3-inch tall gauze element that provides superior filtration compared to standard paper filters. The oval shape is not just for aesthetics; it provides a larger surface area to feed those thirsty 48mm or 51mm bores, ensuring that your engine isn''t gasping for air at high RPMs while keeping harmful road grit out of your precision-tuned venturis.

The engineering behind this unit focuses heavily on the "real world" fitment issues faced by Type 1 Beetle owners. Fitting a massive dual IDA setup often leads to clearance headaches, especially when trying to close the deck lid without using unsightly stand-offs. At 3 inches tall, this air cleaner strikes the perfect balance, offering enough internal volume to house velocity stacks while maintaining a low-profile silhouette that fits comfortably under the hood of most classic VWs. The chrome-plated top and base plates offer a show-quality finish that resists corrosion, making it as much a visual upgrade as it is a mechanical one. Whether you are building a weekend street brawler or a dedicated drag racer, this gauze-element cleaner ensures your IDA setup breathes clean, cool air for maximum combustion efficiency.

PRO TIPS

1. Proper Gauze Maintenance and Oiling

Because this unit uses a gauze-style element, it is essential to treat it correctly to maintain its filtration properties. Unlike paper filters, these are designed to be washed and reused. However, the secret is in the oiling. After cleaning the element with a dedicated gauze cleaner and letting it air dry completely, apply a uniform coat of air filter oil. Don''t over-saturate the element, as excess oil can be sucked into the carburetor, potentially gumming up your air bleeds or jets. A light, even red tint across the entire surface is all you need to trap the fine dust that can cause premature cylinder wall wear.

2. Managing Velocity Stack Clearance

If you are running velocity stacks (air horns) inside your air cleaners, you must verify that there is at least a 1/2-inch to 3/4-inch gap between the top of the stack and the bottom of the air cleaner lid. If the lid is too close to the stack, it creates a restriction that can cause erratic tuning and a "rich" condition at high speeds. With the 3-inch height of this EMPI unit, standard short or medium velocity stacks usually fit perfectly. If you are using tall stacks, you may need to trim them slightly or source a shorter set to ensure the air has enough room to "turn" into the stack opening.

3. Deck Lid Seal and Vibration Check

High-performance IDA engines tend to vibrate more than stock configurations, which can lead to the air cleaner mounting nuts backing off over time. Always use a small drop of blue (removable) thread locker on the mounting studs to ensure the assembly stays secured to the carburetor. Additionally, if you find that the top of the air cleaner is just barely touching the underside of your Beetle''s deck lid, consider installing deck lid stand-offs. This not only prevents the chrome from getting scratched but also creates a "chimney effect" that helps pull hot air out of the engine bay, further improving the density of the air entering your 43-6013-0 air cleaner.
