1.       Release the jubilee clip, which holds down the connecting hose between the airbox and engine, with a Phillips screwdriver. There’s no need to take the clip off.

2.       Release the four screws which are situated on every corner of the airbox cover. Also in this case; there’s no need to take them complete out. After about ten millimeter they’re loose from the lower part of the airbox and will remain in the cover.

3.       Take off the cover, take the original airfilter out and remove eventually any big debri, like leaves.

4.       Put the new (K&N) airfilter in the cover.

Put the cover back on the airbox (don’t forget to put the connecting hose), look if it all fits nicely and tighten the four screws and the jubilee clip.

5.       In the case of a K&N or other aftermarket sport airfilters, put the STOP sticker (with should come with the filter) on the lid of the airbox. When the dealer is doing the maintenance on your car, be aware that some of their mechanics just change them back to OEM and throw them away (Or use it in their own cars). Make a note of it before handing over the keys to not change it!

Follow the instructions which came with the filter to clean it. I recommend you clean every 5,000 km by tapping the larger dirt out and 10,000 a full clean with the recommended cleaner and impregnation oil.
