I always used to serviced my car at Suzuki 7s dealer service center. Its above 26k now, They never changed my AC filter till now Because in PAK wagon R Model there is no option for this, Once of my friend told me i should manually installed an AC filter by myself after cutting a specific area under dash board. By doing this i can safe the life of my blower and save money in future. I need some guidance on it.
