the air intake and exhaust will not give you more power.
it will consume lesser petrol, makes you think that wow, now i lightfoot also got so much power. but conclusion if you heavy foot your engine still spits out maybe extra 3 to 4 horsepower which in car terms, nothing. cold weather also gives you extra 4 to 5 horsepower, change new engine oil also gives you 2 to 3 horsepower.
Example:
step 30% throttle to maintain 60km/h
after modding
step 20% throttle to maintain 60km/h
but if both case you step 100% throttle from 0-100km/h,will be only 0.2 to 0.3 seconds difference
