Dual 40 IDF Carburetor Kit, For Type 2 & 4 VW

OVERVIEW

When it comes to unlocking the latent power hidden within your Type 4 engine, nothing carries the prestige and performance pedigree of a genuine Weber Dual 40 IDF Carburetor Kit. Designed specifically for the robust architecture of the 1700cc, 1800cc, and 2000cc powerplants found in late-model Buses and Transporters, this kit replaces restrictive stock setups with a precision-engineered induction system that delivers immediate throttle response and a significant bump in torque. Whether you are navigating steep mountain passes in a loaded Westfalia or seeking a more spirited commute in a 411 or 412, the 40 IDF provides the perfect balance of fuel atomization and airflow. These aren''t just carburetors; they are a mechanical masterpiece that has defined the air-cooled performance industry for decades, offering a level of reliability and tunability that makes them the gold standard for enthusiasts worldwide.

This comprehensive kit from Appletree Automotive is curated to ensure you spend more time on the road and less time chasing missing hardware. It features a pair of genuine Weber 40mm IDF carburetors that come factory-calibrated for a baseline Type 4 configuration, making them virtually ready for action right out of the box. The inclusion of a heavy-duty hex bar linkage system is a crucial upgrade over inferior pivot-style linkages, providing a rigid and synchronized throttle action that won''t flex or bind under heat. Every component, from the cast aluminum intake manifolds to the high-flow chrome air cleaners and the necessary gaskets, is selected for its durability and fitment. By moving to a dual-carb setup, you eliminate the long, cold intake runners of the stock single-carb system, which significantly reduces "flat spots" and improves cold-start driveability once properly tuned. It''s the ultimate bolt-on performance solution for the serious Type 2 and Type 4 owner who demands the best for their vintage Volkswagen.
