@turbo_charge: I get it that it is called breather filter. You also mentioned that hot gases and oil vapors are exhausted from crankcase. I am confused and pls guide me. Is not exhaust system of engine is responsible to throw each gas and stuff like that outside from the engine or the breathing system you are speaking about is kind of mini exhaust system of the engine?
I have new Mehran with 21,000 KM. Is it wise to upgrade all the things like stock battery, ignition coil, cables, cold air intake, breathing filter etc?
If I go for step by step as I am in short of money
Can I start from installing air breather in it?
