What You'll Learn
The plastic strip is called a front lower valance or air dam
The plastic strip under your car's front bumper is called a front lower valance or air dam. It is added by automakers to protect the bumper from damage. Since bumpers can only absorb minor impacts or scrapes, the plastic strip acts as a buffer and prevents the bumper from getting damaged.
This plastic strip is also known as a deflector strip, and it serves two purposes. Firstly, it changes the air pressure under the car, improving stability at speed. Secondly, it helps divert airflow up to the radiator. This plastic strip is particularly useful for high-riding vehicles like trucks or SUVs as it reduces the aerodynamic ride height of the vehicle without reducing ground clearance.
Despite their benefits, plastic strips are vulnerable to damage as plastic breaks easily. Once the plastic strip breaks, your bumper is exposed and more likely to be damaged. Therefore, it is recommended to swap out the plastic strip for something sturdier, such as an aftermarket valance or a rubber bumper strip.
If you are looking to increase ground clearance, another option is to skip the plastic strip replacement and apply a transparent film over the front bumper. This can be done with a 3M transparent film meant for car hoods. However, this option is expensive and time-consuming.

It protects the bumper from damage
The plastic strip under your car bumper, also known as a front lower valance, air dam, splashguard, or belly pan, serves the important purpose of protecting your bumper from damage. While bumpers are designed to absorb minor impacts and scrapes, they can still be susceptible to damage. The plastic strip acts as a sacrificial layer, taking the brunt of the impact and helping to prevent direct contact with the bumper.
By absorbing the initial force of minor collisions, the plastic strip under your bumper plays a crucial role in maintaining the integrity of your car's exterior. This protective barrier can be the difference between a close call and costly repairs. It is worth noting that these plastic strips are also vulnerable to damage themselves, as plastic can break easily. Therefore, it is important to regularly inspect and, if necessary, replace the plastic strip to ensure your bumper remains well-protected.
One of the key advantages of the plastic strip is its ability to enhance your vehicle's aerodynamic performance. By reducing the amount of air flowing under the car, the plastic strip improves fuel efficiency and stability at speed. Additionally, it can help divert airflow up to the radiator, contributing to optimal engine cooling. This dual functionality of the plastic strip showcases the thoughtful engineering that goes into modern automotive design.
While the plastic strip offers protection, some car owners choose to further enhance their bumper's defence by applying a transparent film. This film provides an additional layer of safeguard against light scrapes and scratches. For those seeking an upgrade, replacing the plastic strip with a rubber bumper strip is an excellent option. Rubber bumper lips offer superior durability and flexibility, bending up against the bumper for improved protection.
In conclusion, the plastic strip under your car bumper serves as a vital line of defence against damage. Its presence not only safeguards your bumper from minor impacts but also contributes to improved aerodynamics and fuel efficiency. With regular maintenance and timely replacements, this unassuming feature ensures that your car remains in optimal condition, protecting both its aesthetic appeal and structural integrity.

It can be replaced with a rubber bumper strip
The plastic strip under your car bumper is called a front lower valance, air dam, splashguard, or deflector strip. It is designed to protect the bumper from damage and absorb minor impacts when bumping into a curb, speed bump, or another object. However, these plastic strips are vulnerable to damage and can break easily, leaving your bumper exposed.
When the plastic strip on your bumper breaks, you can replace it with a rubber bumper strip, which offers improved protection for your bumper. Unlike the plastic strip, a well-made rubber bumper strip will stay intact when dragged over a curb or speed bump. It will even bend up against the bumper, providing enhanced defence. Replacing the plastic strip with a rubber alternative is a cost-effective upgrade that will enhance the resilience of your car's exterior.
There are several options available when replacing a damaged plastic strip. One option is to install an aftermarket valance, which can give your car a unique, sportier look. You can also choose an OEM-style aftermarket valance if you prefer the OEM appearance or are on a budget. However, it's important to note that aftermarket valances may need to be painted before installation, and they are just as susceptible to breaking as OEM valances.
If you're looking for an alternative to replacing the plastic strip, you can skip it entirely and apply a transparent film over the front bumper. This method uses a 3M transparent film designed for car hoods to increase ground clearance and prevent light scrapes and scratches. However, this option is quite expensive and time-consuming to install, and it won't provide protection during a more severe impact.
In conclusion, the plastic strip under your car bumper can be effectively replaced with a rubber bumper strip, offering enhanced protection, durability, and improved aesthetics. This upgrade ensures that your bumper remains intact and well-protected, even when encountering curbs or speed bumps.

It improves fuel efficiency by reducing airflow under the car
The plastic strip under your car's front bumper is called a front lower valance or air dam. Automakers add this to protect the bumper from damage, as bumpers can only absorb minor impacts or scrapes without getting damaged. This plastic strip is also designed to reduce aerodynamic drag by reducing airflow under the car, which improves fuel efficiency.
Air dams are full-width plastic pieces that reduce the aerodynamic ride height of the vehicle without reducing ground clearance. They are commonly found on trucks and SUVs, which have a higher ride height. By reducing the airflow under the car, air dams improve the vehicle's stability at speed and sometimes help divert airflow up to the radiator.
The more air that is allowed to pass under a vehicle, the greater the impact on fuel economy. A lowered front air deflector will reduce airflow and thereby improve fuel economy. This is why large over-the-road trucks have long skirts under the trailers, to improve fuel efficiency.
While these plastic strips can protect the bumper from damage, they are also vulnerable to damage themselves. Plastic breaks easily, so if the strip breaks, the bumper is exposed and more likely to be damaged. There are aftermarket options for replacing the plastic strip with sturdier materials, such as an aluminium skid plate or a rubber bumper strip. These options can provide better protection for the bumper and improve the vehicle's appearance.

It can be replaced with an aftermarket valance for a sportier look
The plastic piece under your car bumper is called a front lower valance, air dam, splashguard, or deflector strip. It is designed to protect your bumper from damage and reduce the aerodynamic ride height of your vehicle. Over time, this plastic piece can fall off or tear off easily, leaving your bumper exposed to damage.
If you're looking to replace the plastic piece under your bumper, one option is to install an aftermarket valance. An aftermarket valance can give your car a sportier and more unique look. It is also a good option if you are on a budget as you can find OEM-style aftermarket valances that match the original look of your car. Keep in mind that you may need to paint your aftermarket valance before installing it, and it has the same chance of breaking as an original equipment manufacturer (OEM) valance.
When choosing an aftermarket valance, you can opt for one that is designed to improve the aerodynamics of your vehicle. This type of valance will help to reduce the aerodynamic ride height of your car, making it more stable at high speeds. Additionally, it can help divert airflow up to the radiator, which can improve engine cooling. If you live in an area with speed bumps or tall curbs, you may want to consider a valance made from a more flexible material that can better withstand contact with these obstacles.
Another option to consider is skipping the plastic strip replacement altogether and instead applying a transparent film over your front bumper. This option can be quite expensive and time-consuming, but it will help protect your bumper from light scrapes and scratches. However, it may not provide sufficient protection in the event of a more significant impact. If you're looking for a more robust solution, you might want to explore alternatives, such as a rubber bumper strip or an aluminium skid plate.
Ultimately, the choice of whether to replace the plastic piece under your bumper with an aftermarket valance depends on your specific needs and preferences. If you value aesthetics and a sportier look, an aftermarket valance could be a great choice. However, if your primary concern is protection from damage, you may want to explore other options that offer more durability and impact resistance.
