been designed especially for the 1½" SU HS4 carburettor.Many SU
HS4 carburettor users will find their car equipped with
pancake air cleaners. These have been popular for many years.
The latest version of these now have highly polished chrome tops and bottoms
and an up-rated air cleaner, allowing better airflow while trapping more dirt.
Very simple to install, they just bolt to the face of the carburettor.
