It's late, so I don't want to head down to the garage to start fooling around with my car, but I was curious if K&N had a filter for the 3 yet. Looks like they don't have one for the 2.3L, but they do have one for the 2.0L.
However, out of curiosity, I also searched up the filter for a 6....and I came up with this:
http://www.knfilterchargers.com/search/product.aspx?Prod=33-2278
And here are the specs:
33-2278 Product Specifications
Product Style: Panel Air Filter
Height: 0.875 in (22 mm)
Outside Length: 12.563 in (319 mm)
Outside Width: 6.875 in (175 mm)
Now, if the filter inside the box of the 3 measures up to be similar, then we have a hit on our hands
