Using this shift knob is easy. Just install it on your Subaru WRX 2002 - 2014's 5 - speed shifter. When driving, enjoy the smooth grip and the stylish look it adds to your car's interior. For maintenance, use a soft cloth to clean the knob regularly. Avoid using harsh chemicals as they may damage the anodized finish or the scratch - resistant coating on the medallion. Be careful not to drop the knob, especially on hard surfaces, as it might cause dents or scratches. Also, keep in mind that the actual product may look a bit different from the generic image, depending on the material and your vehicle model.
