Aeroforce Interceptor Question
 

I recently purchased a aeroforce interceptor cn401 version 3.7 and I actually jumped the gun on it and bought the wrong model for my car.. because I need the pt series. Anyways I have it up on ebay and I have had a few questions asking if the aeroforce is imperial or metric. I looked everywhere on the aeroforce website and can not see any of this info, Any help would be great. Thank you.
