Basic Knowledge for Car Modification


Normally, car modifications can be divided into 3 kinds: functional modification, appearance modification, and performance modification. The result of a car modification represents the owner’s taste and his perception of driving. Nowadays, car modification also added new content: intelligence. However, among all the car modifications, the most exciting thing is the performance modification, which combines the imagination of the owner and the infinite potential of the car to be developed.

Functional Modification

Functional modifications are those that change or add certain features. Installation of the electric tailgate, electric seat, suction door, air conditioners, luggage racks, navigation systems, etc. are all under this category. The Functionalities added to a vehicle that did not exist before is called a function modification.

Take the suction door for example. The theory of the soft close car door is actually that there is an electromagnetic shielding installed on the door frame (or the edge of the door panel). When the door is opened, current flows through the coil to form an electromagnetic field. So When the door is close to the door frame, the door is automatically sucked up due to the magnetic force. There are mainly three advantages of the suction door:

  • When we close the door, there is no need a lot of strength, which increases comfort and elegance, especially for ladies. Even the children and the old can close the door easily.
  • As we don’t close the door with large strength, there is little damage to the door. When we drive our friends to somewhere, they may close the door strongly when getting on/off the car which will surely damage the door.
  • Sometimes, we will forget to lock the door. With the suction door, you don’t need to worry about it anymore. All you need is to close the door gently.

Appearance Modification

The modification of the car appearance has always occupied a very important position. The general appearance modification mainly includes stickers, body painting, car logo, front and rear bars, large enclosure, high tail, open hood, window visor, HID xenon headlights, front Headlight trim panels, front and rear perspective mirrors, lower bodywork, etc. The quickest and easiest way to change the look of the car is to add an aerodynamic kit. The so-called aerodynamic package is commonly known as the big bag, which basically includes the air intake grille, the car side spoiler (side skirt), the rear surround and the rear jammer flow. Adding an aerodynamic package not only makes the car more visible, but also more sporty. The most important thing is to have a good improvement in performance. Adding an aerodynamic kit does not make the car run faster. Strictly speaking, a good kit usually reduces the speed and gives the car a more stable performance.

Performance Modification

  • Engine

Just like the human heart, the engine is the heart of the car, which is the most important part of the car. The most important modification is to increase its output power. The modification methods include: increasing the cylinder diameter, increasing the compression ratio, adding more valves, naturally inhaling to the turbo, etc. You must note that retrofitting the engine is quite dangerous, which can even cause a serious car accident once the engine is damaged.

  • Intake System

The operation of the engine requires a lot of air. The air enters the engine through the air filter firstly, which is the most important part of the intake system. Most configuration in the original factory is a disposable paper filter. The modified product is made of special chemical fiber. The biggest advantage is that the air flow and flow rate into the combustion chamber can be increased by more than 30% while filtering the air. So the fuel is burned more fully.

  • Ignition System

The ignition system is another important element of the engine. It consists of a spark plug and an ignition wire. The original configuration is a single set of wire harnesses. The voltage and current passability and throughput are not satisfactory. The modified ignition system is that high-voltage electric energy generated by the multi-group harness and the high-performance conductive ignition coil of the firewire is transmitted to the spark plug in a large amount timely. The spark plug is the end group of the ignition system. The Mars generated by the electrode ignites the mixed oil and gas to complete the combustion and push the piston to work. The original configuration is the same as the firewire, which is the lowest configuration to reduce costs. If the owner changes the spark wire and spark plug, it will make the car start fast and accelerate fast.

  • Exhaust System

The performance of the exhaust is directly related to the performance of the engine. While the intake air is increasing and the combustion is good, the exhaust efficiency needs to be strengthened too. The high-performance exhaust pipe and silencer becomes the target of the drivers who love driving fast.

  • Modified Brake

In fact, the structural design of the brake system is relatively simple, but the workload of the modification is larger. The quickest and most direct way to improve your braking performance is to change the high-performance brake pads. In addition, if you want to upgrade the brake system, you can also change the high-grade brake oil or replace the metal high-pressure brake oil pipe.
