Stilo Changing Stilo JTD Air filter

The next thing you need to do is unplug the oil trap pipe that feeds into the oil trap underneath the air box.

You need to do this to make room to slide in and out the air filter.

You need to jack up the car (and support it on axel stands for safety )

Then crawl under and underneath the air box you should see this;



just undo the jubilee clip or remove the fiat clip (there is a guide on here about these clips, a found that you could squeeze them together with a pair of long nosed plairs and they would release... however i couldn't get it back on and had to replace it with a jubilee clip.

then pull off the pipe and you will have a clear path or the filter.



now you need to stay under the car and unclip two clips on either side of the air box at the bottom. sorry i didn't take any photos but all you need to do is find the smaller loop on each clip and pull it away from the box, this will then release the tension on the bigger loop which is holding the lid to the body.

Once these are uncliped you will be able to open the box (from underneath the car as the lid pivots on a hinge which is on the top of the box)

I found it openned a little wider if you reached through and pushed the flexi pipe up a little bit. then openned the lid.

you should then be able to remove and replace the air filter quite freely.

To put it all back together just reverse the above stages.

make sure the clips on the air box are secure and the lid is closed properly, then put the oil trap pipe back on then put the MAF housing back in. the MAF housing just goes back in in the reverse order of taking it out, i.e. push the flexi pipe down, put the housing into the air box then compress the flexi part and pull it back over the MAF housing pipe bit, replace the jubilee clip and your done.

i would like to thank all the users who gave me advice on my K&N filter thread.
