Installing Pod Filter on a BA Astina

[i7H ice]

Hey all,

How do I install a pod filter onto my car? Do I need anything other then the pod filter itself? I've heard of some K&N? kits that people have used. Do they have everything I need to install them?

Also on the black air filter box on my BA, there's a few sensors plugged into it. Do I need those?

The owner before me installed that blue pipe I think.
