Using this shift knob is easy. Just replace your old one with this new AutoStyled shift knob in your Subaru WRX from 2002 - 2014. When you're driving, enjoy the smooth grip provided by the Delrin center and the comfortable fit of the aluminum parts. As for maintenance, you can clean it with a soft cloth to keep it looking good. Avoid using harsh chemicals as they might damage the anodized finish or the scratch - resistant coating on the logo. Also, remember that the actual product might look a bit different from the image due to material and vehicle model differences. That's it, and happy driving!
