I have the 11"x8" oval filter set up (from Summit). It initially had a 2" filter but I soon replaced it with a 4" which just fitted under the bonnet. I was amazed at how much the curve in the bonnet would allow.
Your engine is probably in a slightly different position (as they all are) but if you want some measurements, let me know. Just looking at your photos, the 11"x 8"x 2" should fit just fine. My original setup with the 2" filter only had about 3/8" clearance between the top of the MAF setup and the top plate of the filter. Can you get a 3"?
Cheers
