I have a MS3 CAI off a gen 1. It was used for about 40,000 miles. So each air filter has about 20,000 miles on it, probably less. It comes with the air straightener as well as an extra filter. It has some scratches just like any used part should. I might be missing a rubber stopper with a screw in it but I'm not sure if it came with the car or the CAI. $190 shipped.
