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.
