Assalam O Alaikum!
I own a Suzuki Cultus VXR 2005 and I am planning to sell it for a 2010 Liana Eminent. But first I need to maintain it because condition is not satisfactory. I am replacing the following parts:

1. Spark Plugs
2. Air Filter
3. Tyres
4. Brake Oil
5. Gear Oil
6. Engine Gasket
7. Tyres
8. Seat covers

Can anyone please suggest which companies should I consider for each. The budget is limited.
Note:
(a) I want good spark plugs but not the Iridium ones they are very expansive.
(b) Brake oil and Gear Oil is hard to find. Please Suggest.
(c) I always use General Tyre (XP 2000 II) are they sufficient?
(d) I want to do a complete service. Can anyone suggest a good servicer in Karachi?

JazakAllah Khair.
