Up until now, my Isis had run around 70k and never had its air condition serviced, hence I decided to send it for a checkup and maintenance services. In the same time, the air cone filter were changed to a premium Denso filter as shown on the picture.
The filter element are green in colour and it doesn't have any smell to it. I am expecting some green tea smell but it just odourless.
Anyway, remember to service your air-cond every 2 year (maximum) regardless of mileage or 40k whichever earlier. Cost of repairing any parts on your air condition system are expensive based on experience.
Parts number for Denso filter : DCC1004 which will fit to Toyota Wish too.
