Why Choose Genuine Weber?

The market is now flooded with inexpensive copies of these legendary carburettors.

While often sold at attractive prices, these reproductions frequently suffer from:

• Poor manufacturing quality
• Inconsistent machining tolerances
• Inferior materials
• Limited compatibility with genuine Weber components (such as jets, emulsion tubes and venturis)

As a result, these copies can be difficult—or even impossible—to calibrate correctly, leading to poor drivability and reduced engine performance.

Choosing genuine Weber carburettors guarantees original manufacturing quality, full compatibility with genuine Weber replacement parts, and the ability to tune your carburettors precisely to your Mercedes-Benz 190 SL.

NOTE: To get the most out of this conversion, the original intake manifold ports will need to be slightly modified (this is not mandatory but recommended) or replaced with our PAFMG9436 intake manifolds. .

We recommend mounting one of our PAFWFP17303 self-regulating electric pumps with this kit.
