PAFClassic 🇬🇧, official distributor of WEBER and WEBCON brand products.

All the carburetors we offer are genuine WEBERs manufactured in the Magnetti Marelli licensed production plant in Spain.

We have access to over 11,000 references (carburetors and spare parts) as well as the WEBER technical library so that we can provide you with the parts you are looking for for your carburetors.

Make sure you always buy genuine WEBER products like the ones we offer, because copies of these legendary carburetors are now flooding the market.

Often offered at very attractive prices, these copies are often of average manufacturing quality and are not always compatible with genuine WEBER parts (jet sizes for example), therefore not allowing them to be calibrated correctly for your car.
