These jobs as said by others are very basic but it would still be good if you go to some professional mechanic rather than some anaari.
If you wanna go to gulshan, just head to where Mr. Burger was near NIPA and take the first left and ask for Rifaat Mechanic
He will himself arrange for all the necessary genuine parts.
BTW guys why don't you go buy genuine parts from Toyota showrooms? I bought all these filters from Toyota Western Motors when I bought the car.
