Hello, If this has already been discussed then i apologise, i couldnt find it anywhere. I have a 56 plate 1.8 Zetec petrol Focus and yesterday put a Cone KnN air filter on. When i took the top of the air box off i saw that there was a feed from the engine into the bottom of the airbox which ran oil out into a small sponge in the airbox. Anyone know what this is? And will this cone filter affect that? Does it need the suction from the air box to pull the oil through? Cheers.
