1)	Assemble Your Kit + Notes
	Below is the total kit I used. As you can see, there aren't many tools required for this job at all. Change Duration: The Air filter should be replaced no sooner than every 12-18 months, depending on your mileage. *Note:* If your car is not exactly the same model as mine, please check if takes the the rectangle or circle shaped Air Filter.

2)	Engine Cover - Removal
	Remove the engine cover.
1)	2 clips at the front

3)	One large hose on the right

	This is the housing for the Air Filter, the Intake Silencer.

As you can see in this photo, mine had come off, hence when you are putting everything back together, ensure you fit the Vacuum Hose back in!
