Compatibility is Key
One of the first things I learned was the importance of compatibility. Not every rebuild kit will work with all K46 models. I made sure to double-check the part numbers and ensure that the kit I chose was specifically designed for my model. This step saved me from potential headaches down the line.
Quality Over Price
