This aluminum skid plate/splash guard is a direct fit for your Subaru WRX or STI. It replaces the OEM plastic splash guard panel which offers little protection and generally has many problems. It offers built-in trap doors for both oil drain plug and oil filter. Unlike many splash shields and skid plates on the market, this also offers ventilation as well as complete side brackets for additional support. It comes with new hardware - especially important as this goes ALL THE WAY to your front bumper and doesn't stop at the radiator support - it will replace the stock push clips with speed nuts and bolts. This will give your WRX or STI support on the front bumper while maintaining optimal air channeling under the vehicle with this aluminum splash shield. Test off road in mud and various applications - this skid plate will keep your engine bay clean and protect your vital components.
