An engine splash shield is a cover located at the underside of cars. It protects your engine from potential damage caused by bumps, water and debris. Depending on road conditions, stock engine shields can become loose or torn, making them ineffective guards. There are certain considerations when picking replacement shields.
Engine splash shields are not universal. Shields are designed to perfectly fit only specific models. Each shield is fitted with slots and grooves suited for a model's engine protection and air flow. Unless you can drive peacefully knowing your car is in danger because of the wrong engine shield, make sure that whatever shield you are buying is the right one for your car.
Most engine splash shields are made of high density plastics or fiberglass. These types of shields offer a great balance between durability and protection. They are ideal mostly for cars driving under ideal conditions. However, if you happen to unfortunately bump the underside of your car, go through intense floods, or just pass through a very rocky road, chances are these light shields will be damaged.
For a more durable choice, try metal or aluminum shields. More expensive, these tougher shields offer better protection against foreign objects compared to their plastic counterparts. Take note that this heavier guard will add extra weight and alter alter the balance your car.
A complete seal of the engine's underside for protection will increase the engine's temperature to dangerous levels. To combat this, engine splash shields are strategically fitted with slots to ensure smooth air flow in and out of the engine compartment. For more air, dual sheet shields enhance air flow compared to a single sheet while keeping its ability to protect the engine.
