So I just had Z1 full cold air intake and a FI oil cooler installed yesterday, and won't need my Stillen Gen 2s anymore. These were on the car for about 12,000 miles.
Overall they are in great shape with a couple dings in the filter from where it rests on the interior of the engine bay when installed. If you want a more aggressive intake over the stock boxes, but don't want to have to drop the bumper this is a nice option.
Still have the box they shipped in, and will come with the Stillen tubes, filters, couplers, and clamps - everything you need to bolt up to your car.
I will post photos as soon as I wipe them down, and can get them uploaded. You can find
full info here.
Price: $250 plus shipping and fees.
