Seen them mentioned... wondering what they are.

A Fogged Air box is simply the stock air box that a 4" hole is cut and a similar size hose is run from the box to behind the driver side Fog light. The original setup on my 1.9L had a 2" or so hole in the airbox and the horn and hose was routed over the top of the radiator and ending on the passenger side where the air was drawn in, very inefficient at best. The advantage of the Fogg, a lot more direct air volume coming into the system and cooler air which is what a induction system wants. I had my done a month or so ago and what a different in acceleration especially after the 4K RPM range. I also added Bosch Plus 4 plugs and combination of the two really made a big difference in the car performance, from my seat of the pants view.
