1. Intake systems
Intake systems are designed to ensure that the
correct air/fuel ratio is available to the engine for the
cleanest burn to minimise exhaust emissions.
Systems that provide excess air or fuel can create
high exhaust emissions from the vehicle. Fuel or
other hydrocarbon vapour that escapes as
evaporative emissions can lead to the formation of
photochemical smog.
Replacement air cleaners are permitted provided
that they have all connections and systems present
on the original air cleaner and operate in an
identical manner.
(a) Open element or pod type air cleaners on
carburetted vehicles are not permitted.
(b) Dry element pod type air cleaners are
permitted on EFI vehicles. Oiled, oil-soaked or
fluid-treated elements are not permitted. Any
sensors integral to the original system must
be retrofitted to the same approximate
location.
