is it really gonna make a huge difference on the 1.2? i've got a greens cotton induction kit on mine without any cold air feed. if i fed cold air to it would i notice any performance difference. i only really got it for the cool sound!
The fiat system is actually quite effective at getting cold air to the filter. You want the air as cool as possible as hot air is not as dense (thats why hot air balloons go up!) so the engine cannot burn as much fuel.
Depending on the temperature you could easily loose 5-10bhp.
5-10bhp? oh crap! well i haven't removed the air box - its still there in the wing. so cold air is still coming into the engine bay. i just removed the pipe that goes across to the engine to get the induction kit in. what if i re-attach the pipe (or something similar) and run it upto the new filter? i guess some sort of heat shielding for the filter would also be a good idea?
