Shift knob upgrades offer a number of advantages over a base model knob - better feel, weighted knobs reduce shifting effort, and appearance. A stock leather knob is one of the first items to show significant wear and is an indicator to how the owner treats their car. We offer factory BMW and quality aftermarket knobs and boots that enhance your driving experience and improve the quality of your interior. Unless shown, BMW shift knobs are sold without a boot. Take note of your stock boot and knob configuration.
