Getting that Filter Box out! Alfa 156

Hi All

Another filter box with sheared and spinning bolts I'm afraid!

I've decided to save money and take the airbox out. I'll replace the bolts, etc when it's out of the car - I'm happy to do that.

My question is: After clearing all the obstructions and pipes above the filter box how does the filter box come out? I can see that the bottom of the filter seems to have rubber bits that just sit onto holes in a bracket under the car, but how does the exit pipe in the side of the filter fit into the box that seems to sit under the wing?

Is it just a push fit? So do I just rock the filter box away from the wing and lift out?

Would like to know before I start ripping!

The snorkel is a push-fit on the JTD and V6, not sure about the TS though.

Maneuvered mine out and it's a pig of a job.

I have a cone filter available if you want to replace the box for something sporty

I thought you meant pollen filter, took me a while to figure it out...

Better take out the battery completely so you get a better view and wiggle room.

Are you replacing it or you intend to remove it completely? You need to have a air filter, and on a TS, IMHO the standard intake is the best option, short of a real professional intake (not found at your local store) that does not serve anything without other mods. I've seen countless ricer solutions fail completely to get cold air because they are not tailor made for the TS engine compartment.

i removed mine...

yes, the side snorkel is just fitted on, just yank it off and leave it in situ,... under the car you need to unplug those rubber feet and push the box up - u really need another person from above to guide it out.... then u can access those 3 bolts easily...

obviously u need to remove the afm and induction pipe first...

but yes, the stock airbox will pull out from above, with much swearing and gnashing of teeth...

I took mine off when replacing the elbow on the bottom rad, on a JTS. Removed air pipe, remove the fuses by battery, unbolt support bracket, unbolt the lid and remove maf, pipe and filter, remove the plastic cover on the right hand side of the battery so that you can get your hand down into the wing and pull/push/pull the intake while lifting the airbox, once I got the intake off I dropped the box under the car.

Much similar to what wankski sad above really.

On a TS their is a large resonator unit inside the inner wing where the V6/GTA pipe is on the larger engined cars. It takes a bit of pulling about to get the two to part company and is best from below with the undertray off (if fitted).

If you do get it all out, then is a good time to ditch the TS resonator and fit a GTA (or V6) pipe. The standard airbox with a cleaner intake pipe is a big improvement and the air is still being taken from a place where the air is cool rather than from the hot engine bay.
