They let me take my Stillen G3 intakes off my totaled Z today. They weren't damaged in the accident, but one of the K&N filters is missing.
The intake tubes have some usual scratches/rub marks on them but have no holes, and are not bent in any way.
The K&N filter (part number
RU-2820) can be had from Stillen for $39 or you can find it pretty much anywhere else online.
The other thing you'll need is one of the clamps that goes over the filter (Stillen part # 405030-5) which is $2 from them.
SOLD! Only took 2 mins.. impressive
