Using your HT Autos rear diffuser is easy. First, check if your vehicle is the right model (2002 - 2007 Subaru WRX Sedans or 2004 - 2007 Subaru STI Sedans, and note it doesn't fit hatchbacks). When installing, you'll need to drill small holes in the underside of the bumper and the spare tire well. Make sure to use the included installation hardware. If you have a larger aftermarket muffler or other mods like tow hooks, you may need to trim the diffuser for it to fit properly. For maintenance, simply clean it regularly with a mild soap and water solution. Avoid using harsh chemicals that could damage the black finish or the durable ABS plastic construction. Keep it in good condition, and it will continue to improve your car's aerodynamics and look for a long time.
