Chrome Oval Air Filter - IDF Carburettor Air Filter - (83mm Or 3.27inch Tall)

Performance oval air filter assembly designed for use with twin carburettor setups including Weber IDF, Dellorto DRLA and HPMX carburettors. With an approximate height of 83mm (3¼”–3½”), this filter offers improved airflow while maintaining effective filtration for both road and performance engines.

Air filters are essential for protecting your engine from dust, dirt and debris. This unit uses a high-quality washable cotton gauze element, allowing increased airflow compared to standard paper filters while still providing excellent filtration. This helps improve throttle response and overall engine efficiency, particularly on tuned aircooled engines.

The oval design provides a larger surface area than smaller round filters, improving airflow capacity while still fitting neatly within most engine bays. The chrome top and base plates give a clean, classic performance look, ideal for show cars and engine bay upgrades.

This filter is fully reusable—simply clean and re-oil the element as part of routine maintenance, making it a cost-effective long-term solution.
