me basic questions lang po sana akong tatanungin about aircons(mods paki-move na lang if this is in the wrong forum):

1. when you say na nippon-denso aircon mo, which specific component ng aircon are you referring to, e.g. compressor, evaporator?

2. Anu anong brands meron? ang alam ko lang is denso, sanden, calsonic

3. Are there any aftermarket(not surplus) calsonic aircons available, or talagang OEM for Nissan lang un?

4. any ballpark figure as to how much gas the aircon consumes?

5. me "standard" sizes ba sya, or specific sya to the year/model of your car?
