Hello,
I was wondering if somebody could help me, I have Alfa Mito 0.9 Twin air, I have read that the strainer filter should be cleaned every oil change. Does anyone know where it is on the engine.

Many Thanks
John.

This is what you require, as for its position I can’t help.


This from Fiat Forum as the twin air is used in the 500 too. Go to post #13 for a guide on how to do it. Further posts show a different cap over it. The strainer fits vertically at the rear of the head whereas on the Multiair it is at the cam belt end of the head and fits horizontally.

I came across this thread trying to find information on where the strainer is on my Twin Air Mito. However, the linked Fiat page (for me anyway) seems a bit of a mix of Multi air and Twin air, so I'm unclear as to where it is. Sadly no Youtube videos either. I haven't got a workshop manual yet, but I don't think there is one for the Mito anyway, at least not a Haynes one?

Just wanted to take mine out to check as the dealers supposedly changed it when they serviced the car before I bought it, but looking at the colour of the oil I'm not convinced they even changed the oil...

Just to update this thread I have found, removed and checked my Twin Air strainer. Photos below to save anyone having to go to the Fiat forum:

Location of the cap covering the strainer. Just behind the coil packs and in front of the air filter housing mounting spigot, circled in orange:

Cap removed by turning about 1/8 turn anticlockwise then levering it up and out to reveal the top of the strainer:

A thin walled 15mm socket just fits down the hole, which luckily I already had. Some additional cable ties round the coil pack connectors I guess to hold them on securely, so have left them in place:

Then removed:

Strainer was nice and clean (dealer had replaced it before sale, but being a cynic I wanted to check :p):

From the bottom end:

Reverse side of the cap that covers the strainer:

I hope this is of use to other Twin Air owners who might want to check/clean theirs. (y)

I did it today. Thanks again for this awesome manual. But can anyone tell me why there is so much oil between cap and filter? Where does it come from? Nevertheless, the filter looked clean, but I cleaned it and the cap again with some brake cleaner spray.
