Sports Air Filters

Are you achieving the full potential of your present carburettors???

The full airflow potential of your carburettor(s) may be limited by rhe contraction effect in the inlet airstream caused by an abrupt entry into the carburettor mouth.

INCREASED AIRFLOW CAN INCREASE POWER POTENTIAL
Flow bench tests have proven that a suitably shaped entry to the carburettor can result in a gain of 6% in airflow over a straight carburettor entry and almost 12% over a straight 'ram' tube.

COLD AIR INDUCTION SYSTEMS

Many modern mid-engined sports cars can suffer from loss of inlet air density due to inhaling hot engine compartment air.
When increased performance is sought, most enthusiasts seek a less restrictive air filter system than factory plastic boxes.

In these installations there is usually a vent in the side of the car body to assist in delivering ventilation to this hot environment.
Why not take advantage of this ? - place a pod filter in this area and lead this cooler air direct to the throttle body.
Given this opportunity, why not use a thermal barrier on the tube to further reduce the tendency for heat transfer??

That's exactly what we did.HP Hi-Flow Cold Air Induction Kits for MG F Image copyright (c) 2011.
