Bro that is what i am saying, exactly same air filter was available at bismillah for 500rs while shell f6 sold it for 650.
Yes i am also worried about oil, actually i was previously using total quartz 9000 5w30 and had good results with it so i thought of trying shell 5w30 but it seems engine does not like shell 
Before total i was using honda genuine oil 10w30. If 5w30 experiment works fine, then i will stick to 5w40 or 10w30 in a good brand. 10w40 is too heavy
Yes like i said, he showed me 4 different qualities but nissin japan he gave me for 1700. Same price was quoted by aqash, either bismillah guy gave me copy saying its japanese or he gave you at a much higher price. Do you have any pics of original nissin japan pics?
