Why Aren't Cars Equipped with Bug Screens from the Factory?
2 Answers
Cars are not equipped with bug screens from the factory for the following reasons: The installation of a bug screen on a car is optional, as driving needs vary among different car owners. If you frequently drive on highways or in areas with a high number of insects, installation is recommended; otherwise, it is unnecessary. Below is an introduction to car bug screens: 1. Definition and Function of Car Bug Screens: A bug screen is a very fine protective mesh that, once installed, can block flying insects, fluff, small stones, etc., from impacting and clogging the radiator fins. 2. Considerations: After installing a car bug screen, owners should regularly remove and clean the protective mesh to prevent excessive accumulation of debris from affecting the radiator's cooling efficiency.
Car manufacturers do not install grille guards from the factory mainly due to practical usage and design balance considerations. As a seasoned long-distance driver who frequently travels to remote areas, the insect issue is indeed annoying. However, there are several reasons why original equipment manufacturers (OEMs) avoid installing grille guards: First is cost control—adding a mesh may not be expensive individually, but for mass production, every small component accumulates and increases the final price. Second is airflow impact—grille guards obstruct air intake to the radiator, potentially causing overheating during high-speed driving in summer and leading to engine damage, which is counterproductive. Third is maintenance—during bug-heavy seasons, the mesh can get clogged with dead insects and dust; if not cleaned promptly, it may block heat dissipation. I’ve seen cases in Northeast China where drivers installed aftermarket guards but neglected cleaning, resulting in radiator failure. Therefore, automakers leave the decision to us—buying and installing an accessory when needed offers flexibility and convenience. For long-term drivers, it’s best to inspect the setup seasonally to prevent minor issues from escalating into major failures.
