This is a used 2012 Kia Optima stock filter assembly. It looks a little dirty but it's been wiped down and now stays in the garage. This stock assembly includes a washable K&N filter. I upgraded to a Injen ram air intake and I don't need this anymore. I believe the K&N filter alone was $65. That filter has about 4,000 miles on it.
UPDATE: I recently installed a 3.0 Magna Flo exhaust pipe on my car. Now I have the stock 2.5 pipe and the stock intake filter assembly ready to sell. I could keep it here as back up parts but I would rather sell it and have more garage space. The stock pipe is a single pipe from the manifold then it splits in two and has 4 exhaust tips (Two tips from each pipe). These parts have about 52,000 miles on them. No rust!
