This boot will almost always be ripped on cars older than 4-5 years, leading to a loss of fluid in the shift turret and notchy shifting.
This is an NC 5-speed part, but will also fit 1993-05 cars with both 5- and 6-speed transmissions. As a bonus, it's considerably less expensive!
OE Mazda part. Mazda part number R501-17-47Z
