ACTUAL HOW TO
On the 1.4 16v engine, the air filter is contained within the engine cover. The FIRST step is to remove this cover. Itis held in place by 4 pressure pads roughly dotted evenly around the covers edge. It is a simple case of gripping the cover firmly and pulling up wards.

[TIP] The screws in the under-housing wont actually come all the way out, they remain in place, so don't worry.
You simply lift out the old filter, clean the housing (as necc.) and refit the new one, tightening screws as you go.
First, ignore the dirt on the leading edge of the air filter pleats. All air filters accumulate dirt on the leading edges in as little as a few thousand miles. Yet most last for about 12,000 miles. You want to know how much dirt has penetrated deep into the pleats. To test the true condition of your filter, hold a shop light behind it. See how much light passes through the inner pleats and compare yours with the three sample photos below.
The filter shown on the left is totally clogged and cost the owner a fortune in wasted gas. The filter in the middle shows a clogged area, but the rest of the filter has decent light transmission. It’s borderline, and the owner could probably squeeze 2,000 to 3,000 more miles out of it. It should be replaced at the next oil change interval. The filter on the right shows how much light passes through a new filter.
