Air Filter (Jap part number) costed me 1400 from Hamza Younas Autos @ Saddar. Thai Air filter was in 1200. I don't know why 3S sells these parts so high in price.
I am not sure whether I mentioned this before or not, @StrikerX @Cr33D , the original lights that come in Axio, for the headlights are 55W-60 or such, I don't remember right now but those were not available anywhere in new. Instead 90W are being sold everywhere in part shops and they will tell you that they are okay to use but nope, they are not. They generate more heat and take more power. The power part might not be an issue but heat shall be, it will bend the headlight plastic.
The 55-60 replacement light (the exact as written on genuine light from Axio, too lazy to look up the exact) I ended up finding in none other than 3S for 350 a piece, right now I believe they are for 450 a piece.
Another thing that I'd purchase from 3S part shop is the wiper blades. Outside in part shops, they sell the rubber only for like 2000+ a set while in 3S I think the whole blade set is for 2500 or such.
