Hello everyone,

Do you know if there is a high performance alternative for the oem filter in the carbureted 326/6? I want to keep the original air filter housing but want a filter thar can manage more airflow.

thanks

Buy a quality manufacterer filter like Hengst or Mann, and you're good to go. The Solex 4A1 with manifold is the restricting factor.
