Twin Genuine Weber 48 IDF Carburetor Complete Kit
Classic Aircooled VW Carburetors and Kits parts by Limebug
Only serious engine builders need apply! Dual 48 IDFs are a little rough for street use but come out of the gate like a rocket.
If your looking for mid-range and upper end power, Dual 48 IDFs should be on your shopping list.
They work best on engines with stroker cranks and big valves. The installation and tuning of a set of Dual 48s is simplified by the use of our superb Crossbar Linkage.
