Air intake system (such as mushroom head)

Increase the air intake and reduce the temperature, significantly increase horsepower) 2.

Exhaust system (air intake and exhaust are added at the same time. If you change it here, the sound of the throttle will be very nice ~ significantly improve horsepower) 3

Ecu chip (replace or rewrite the original chip)

It may affect future after-sales maintenance. . You can also buy the kind of plug-in pendant that controls fuel injection and spark plug, which is cheaper ~ significantly improves horsepower) 4

Spark plug,

Spark plug wire (enhanced horsepower) 5

Throttle (small cost modification to improve horsepower) 4

Suspension spring (lifting control type) 5

Brake,

flywheel

(Improve mobility) 6

Turbocharging (a big increase in horsepower)

But it's expensive

Get more than 20 thousand) 7

Nitrogen nos

(This is not explained.

Anyone who has played the game knows)

In short, without changing the engine modification,

How to let more air in and out of the engine,

It is an effective promotion of power ~!
