Hi,
Its an accepted fact that engines perform better with cold air intakes.
So why do a lot of older cars, such as the Ford Fiesta have air intakes with the feeds directly off the exhaust manifold?
Some older cars, Toyota 1000 for example even had a summer and winter setting allowing you to point the inlet at the manifold in winter time?
Ive never understood the point?
