A clogged air filter element often shows up as a richer running and poorer top speed, and on the B20B with carburettors and a preheating system a tight filter housing is crucial for a stable fuel mixture to the SU carburettors. This category gathers the parts around that very filter housing – from the element itself to seals and mounting hardware.

The group includes the air filter element, gasket, air intake hose and hose clamp plus clamp, flange screw, screw and a complete mounting kit. The B20B arrived on the 1800S from model year 1969 (chassis #28300) and kept the carburetor technology, unlike the later fuel-injected B20E. Check that the preheating hose and flanges seal tightly – false air past a tired gasket is a common point to inspect with an uneven idle. Always compare the design against your car so that the element and mounting match the carburetor version.
