Weber 48 IDA Carburettor Base Gaskets

High quality fibre base gasket set designed to seal the carburettor to inlet manifold joint on engines running Weber IDA carburettors. Supplied as a pair, these gaskets are essential for high-performance twin carb setups on aircooled VW engines.

The carburettor base gasket is a vital component in maintaining an airtight seal between the carb and manifold. On performance setups using IDA carburettors, even the smallest air leak can significantly affect tuning, causing erratic idle, flat spots and reduced power. These gaskets ensure that all incoming air is properly metered through the carburettor, allowing precise fuel delivery and maximum engine efficiency.

Manufactured from durable fibre material, these gaskets are built to withstand the increased heat, fuel exposure and vibration associated with high-performance engines. Designed with the correct stud spacing for Weber IDA carburettors, they provide accurate fitment for race and fast road applications.

How It Works
These gaskets sit between the carburettor base and inlet manifold flange. When tightened down, they compress to create a tight, sealed joint. This prevents unmetered air entering the engine, ensuring stable idle, accurate fuel mixture and consistent high-performance operation.
