Is car tuning profitable?

1. Power: generally upgrade power first from the exhaust to start, the order is the tail section, the tail section, the whole section. Generally, if the whole section is changed, it is necessary to upgrade with the computer program. Of course, there are also sports three-way catalytic upgrade. Then the intake system can be replaced with a larger intake "mushroom head". The big manufacturers also have a special intake guide kit for the car. Then add or replace the intercooler, add oil cooling, pressure relief valve and so on. These are simple upgrades. For higher requirements, you can replace the turbo, expand the cylinder, etc.

2. Handling: from the simplest addition of reinforcements, to upgrading stabilizer bars, wheels, tires, to replacing shocks, brakes and so on.

3. Appearance: all kinds of flower pulling is of course the longest to see, there is also the whole car color change, increase the tail (strictly speaking, add tail should be counted in the control, but the current domestic market add tail is basically to look good ......), front and rear surroundings (the same as the tail).

4. audio and video: the simplest is to upgrade the DVD navigation, and then upgrade the sound, add amplifier, add subwoofer, do modeling, lighting and so on. You can even add a battery and upgrade the generator system.

5. Comfort: upgrading shock absorbers can also be counted in this category, but the current upgrade of shock absorbers are in order to get better cornering performance, that is, the shock absorbers adjusted to the more hard, cornering performance will be very good, but the comfort will be reduced. But some people will adjust it to be softer in normal times and then adjust it to be stiffer when there are races. Yes, it's good to be able to be soft and hard~~ There are seat ventilation and other modifications now too.

All in all, buying a car is like buying a simple house. Anyone with special needs can modify it as they wish
