1971–1974 VW Beetle Ghia Thing Weber 32/36 DFEV Progressive Carburetor
Upgrade your 1971–1974 Volkswagen with this Weber 32/36 DFEV progressive two-barrel carburetor — crisp throttle response, improved drivability, and power delivered exactly when you need it.
The Weber 32/36 DFEV is one of the most respected aftermarket carburetor upgrades available for an Air Cooled Volkswagen — and the progressive throttle design is exactly why. One barrel handles fuel-efficient cruising at light throttle while the second barrel opens under load, delivering additional power and airflow only when the engine demands it. The result is better throttle response, improved drivability, and dependable performance across the full RPM range.
