Using your Billetworkz shift knob is easy. Just replace your original OEM shift knob with this one. Make sure your car is in park or neutral and the engine is off before installation. When driving, enjoy the smooth shifting experience and the style it adds to your interior. Note that this shift knob is only for 6 - speed manual transmission models. Do not try to install it on CVT or automatic transmission cars. To maintain your shift knob, clean it regularly with a soft, dry cloth. Avoid using harsh chemicals or abrasive materials as they may damage the powder - coated finish and the laser - engraved pattern and logo.
