What is the function of a front splitter?

The function of a front splitter is decorative. Adding a front splitter can make the vehicle look more aesthetically pleasing. In reality, the effect of modifying a front splitter is not significant; it merely adds a bit of personality to the exterior. Vehicle modification refers to altering the external appearance, interior styling, and mechanical performance of the original vehicle produced by the manufacturer, based on the needs of the car owner. It mainly includes two types: body modification and power modification. The materials used for front splitters include resin fiber (fiberglass), one-time molded PP material, and PU material. PU material, which is soft rubber, is most commonly used. It is highly flexible, resistant to scratches and damage, but cannot withstand high-temperature paint baking as it is prone to deformation. It is quite thick and heavy.
After years of modifying cars, I've found that front splitters serve three main purposes. First, they improve stability at high speeds by directing airflow downward, increasing front-end downforce—especially noticeable when cornering, as the steering feels more planted. Second, they protect the bumper. Curbs and parking lot stoppers often scrape the front underside, and a splitter acts as the first line of defense. Replacing a splitter is far cheaper than repainting an entire bumper. Third, of course, is the aesthetic upgrade. Choosing a carbon fiber or matte black style instantly gives the car a lower, more aggressive stance, and installation is straightforward—just find a reputable shop and it’s done in half an hour. However, be aware that splitters reduce ground clearance, so approach steep inclines at the right angle.
