2.0D 7th Gen Corolla's Evaporator+Blower was used.
It is very easy to fit, no alterations on the stock unit. Stock evaporator including the chiller box is replaced by corolla's.
No alterations or cutting involved in dashboard, or the stock unit, Heater and ducts.
Blow speed is increased by at least 4 times as compared to stock, so is the cooling, since the evaporator is bigger in size.
