Shift knob designed for e90 but may fit others. Clips on and does not rotate (careful of breakage if you try to twist it!) Fits fine, but is a bit light. Would be a nice print in transparent colors. Difficult to remove without breaking the teeth! (the knob teeth not yours) Please share your makes :) Use cabin-heat-resistant material, dry-fit the part and verify secure retention and unobstructed operation.
