Is it really this difficult to replace the air filter?

 

The V12 is very easy to replace air filters .

Not sure about the 6 cylinder engine, helps if you can be more specific about engine in your model XJS

 

Yes the 12 is pretty easy. The filter box on the 4.0l is lodged between other parts in such a way as to make the job fairly complicated....unless I'm missing something... Added a pic.

 

aaf8,

Yes, the AJ6 / AJ16 is a bit of a pain. I (carefully) undo the butterfly nuts on the inner wing. Be careful, it's easy to rip out the rubber mounts! I also remove the air intake trumpet on the top rad valance - that can be a pain in itself. It's then much easier to remove the joint to the MAF and remove the canister.

Hope that helps

Paul

 

That's what I was afraid of.

Thanks Paul.
