Selling my brand new (new design) Arm Motorsports cold air intake system. I had the older version installed in my car and I kept kicking the 02 sensor check engine light. I reached out to Arm Motorsports and told them the issue and they said that it's happening b/c of the placement of the sensor so they came up with a new design and shipped it to me free of cost. I ended up selling my car before I installed it. ( I actually I tried to install it one day but change me my mind, so it might have a scuff on one of the pipes). So it's been siting in my garage for months collecting dust. Take it off my hands for $300
