45 DCOE 152 - 4 Progression Holes - Genuine Weber Carburettor

$850.00

The Weber 45 DCOE is one of the most iconic side-draught carburettors ever produced—known for its razor-sharp throttle response, exceptional airflow, and unbeatable tuning flexibility. This specific 4 progression hole variant offers enhanced low-to-mid throttle transition, providing smoother drivability and superior fuel metering compared to earlier designs.

A great choice for larger 4 cylinder high-output engines (adaptable to 6 and some 8 cylinders), the 45 DCOE delivers outstanding top-end power while maintaining precise control across the entire RPM range. Its modular jetting system and fully adjustable setup make it a favourite among tuners, race teams, and enthusiasts building classic performance engines.

Whether used alone or as part of a full multi-carb setup, the Weber 45 DCOE offers a perfect balance of race-proven performance, reliability, and tunability.

Key Features:

  • 4 progression hole design for smoother transition and refined part-throttle drivability
  • Fully tunable with interchangeable jets, chokes, emulsion tubes, and venturis 
  • High-flow side-draught layout ideal for performance and motorsport applications
  • Crisp, immediate throttle response across all RPM ranges
  • Proven motorsport pedigree—a favourite on classic racing and high-performance engines
  • Durable Weber construction built to handle demanding conditions
  • Suitable for multi-carb setups on engines requiring high airflow (dual or triple configurations)

The greatest feature of this carburettor is its ease of turnability - with most setting accessible whilst installed.
