Atlas uses guard filters as OEM - both for oil and air.
and for MANN - you have to buy a box of 20 at least (I buy the oldschool 100mm Accord filter - as I need it for Honda Accord anyway) - I buy them and split between 4 freinds - cost about Rs 350/- per piece after everything.
For my Golf its filter is readily available anywhere - it uses a huge MANN 940 lube filter which is also used in Massey Ferguson Tractors and older Hiace 2.2 vans, a number of industrial generators - (costs Rs 550/- per piece) - If I want cheaper - the list in descending.
Donaldson - WIX -
Fleetguard - Crosland
Guard - Qaim - Micro
2 no. guard
20 no. micro - Rs 80/- I wonder if it even has filter paper in it (tractor shop)
Its also annoying sometimes for my freinds to wait in the car at Plaza or a big truck stand/industrial supply shop theres one in Korangi Industrial Area. To buy one oil filter - kehtay hain abay itna chooha engine hai filter capacity khud aik liter hai.
