Do I have to take off the front wheel to change my air filter or can I turn the wheel to one side or the other and still gain access?

 

Easier to take the wheel off; not a big deal ! You can check your brake pads at same time.
That's Jaguar progress; on the XK8 air cleaner access very simple BUT not the A/C filter.
Over way around for XK's!! One day they will get it right, maybe!
To be honest, on the Acura MDX you have to use a hack saw to access A/C filter element! but only the first time!!

Cheers and have a cup of cheer, Adrian
