Intake Manifold, Universal for 30, 31 & 34 Solex Or Brosol

OVERVIEW

When you''re building or maintaining a classic air-cooled VW engine, flexibility is key, especially when dealing with the various carburetor sizes used throughout the decades, such as the 30 PICT-1, 31 PICT-3, or the larger 34 PICT-3. This universal intake manifold is engineered by IAP to eliminate the headache of sourcing specific adapters or hunting for rare, used OEM units that are often pitted, clogged, or warped beyond repair. By featuring a precision-engineered dual-drilled flange, this manifold allows for a seamless, bolt-on installation of the most popular Solex and Brosol carburetors used on Type 1 engines. Whether you''re upgrading a 1300cc engine to a 1600cc powerhouse or simply replacing a cracked original component to chase down a persistent vacuum leak, this manifold provides a robust, reliable foundation for your fuel delivery system.

Performance in a Volkswagen engine isn''t just about the volume of fuel; it''s about the quality and temperature of the air-fuel mixture reaching the cylinder heads. This unit includes integrated heat risers, which are critical for preventing "carburetor icing" during cold weather and ensuring proper fuel atomization for a smooth idle and consistent throttle response. The casting is notably clean and smooth, reducing internal turbulence compared to older, corroded stock manifolds. We have included the necessary gaskets and plugs to ensure you have the essential components required for a professional-grade installation right out of the box. Please note that while the vacuum port boss is present on the casting as per the original design, it is not pre-drilled, giving the builder the choice to run a modern centrifugal advance distributor or drill it out for applications requiring a specific manifold vacuum signal.
