Replacing air filter

Do you know that using a clogged or dirty air filter will affect your fuel consumption ? Thats what happening to my car now. It clock 30k and I haven't change my air filter from day 1, so recently I went to my favourite spare part shop in Sentul and bought myself a Original Air Filter for Toyota Isis. I do expect that the air filter is the same parts as being used in the 1.8l Toyota Wish, after checking the parts catalogue the boss told me that it is the same. The air filter cost RM70.00 and made by Denso Japan. Parts number is 17801-22020.

I had snapped some photo of the before and after condition of the air filter. The darker on the top air filter is the original and replaced air filter while the bottom white colour is the new air filter. I yet to test the mileage I will get after changing this, but I expect some slight increase in power and mileage. For those who experience some drop in performance and mileage per tank, try to check your air filter and replace if necessary. Happy DIY.
