As mentioned earlier, people replace their car grilles for two reasons; better airflow or aesthetics. Both are fine, as long as the grilles fit the vehicle perfectly. If you're looking for maximum protection from the elements, choose a grill with a powder-coated finish. Opt for a chrome or carbon fiber grill for a more stylish look.
Another thing you'd want to consider is the ease of installation, especially if you have a grille guard installed. Thankfully, most grilles are easy to install - it may take some minutes or an hour, but even a novice should be able to install it with the right installation instructions. If you're worried about making a permanent modification to your Bronco, remember that you can easily remove most grilles if you decide to change looks.
Apart from improving the looks of your vehicle, a good grille can also increase airflow into the engine bay. We recommend looking at the grille specifications of your choice to ensure that they'll fit your Bronco. Most of the grilles are easy to install, so you're covered!
