I can't find a cabin air filter online for my 2013 Energi with 'Activated Charcoal' aka Carbon. Has anyone found one and if so details please! thanks! Also, Are 2013, 2014, 2015, 2016 filters all the same size? What about 2012, because i can find one for that (previous body style) year? BTW There is an unholy funk in the vetilation system... Any suggestions would be great! Mine was built in february and i dont know the status of the work on the related TSB as i got it as a lease return.
