This OEM Mazda Factory Replacement upper shift boot fits all 1990-2005 Mazda Miatas. This is the part you see when you remove the center console trim around your shifter. Also known as an "insulator" in your factory service manual, this keeps the dust and fumes out of your driver compartment, but is also one of the first parts to wear out on your Miata. Replacing it is easy, and it will tighten up your shifter if your previous boot was torn. This part is not a cheap replacement, it is a factory Mazda replacement part.
