Using this AutoStyled shift knob is easy. Just install it in place of your old shift knob in your Subaru WRX from 2002 - 2014. When you're driving, the heavy stainless - steel center gives you good leverage to shift gears smoothly. As for maintenance, keep it clean with a soft, dry cloth. Avoid using harsh chemicals as they may damage the anodized finish on the aluminum parts or the scratch - resistant coating on the logo. Also, be careful when handling the embossed aluminum medallion to prevent any dents or scratches. If you notice any loose parts, check the installation to make sure everything is secure.
