Hi, I have a 2008 Toyota vios 1.5g mt. Ok naman yung ride nya... very smooth plus the engine's performance is actually great considering that it's just a 1.5... My inquiry is if I want it to have more power (meaning I want it to be faster) what are the performance parts that I should add or replace? Oh, the condition is that the fuel consumption should not change or if it does, it will become better. So most likely these will be the air circulation parts such as exhaust and intakes.

Thats my personal project for next year.. hehehe
