So I decided on the first basic modification on my ride would be an aftermarket drop in air filter. After doing much research and reading through so many automotive forums, decided to go for K&N's high flow drop in air filter.
Even if its just a filter, it cost RM 250. WTF
I'm pretty glad the warranty for the Vios is over, I waited 2 years to finally do whatever performance changes to the car. So far the pick up response of the car is better than the stock settings (I mean, RM 250 and no improvement is pretty much bullshit huh?)
Didn't really affect the fuel consumption. Still pumping once a week for now.
