Large shifter boot, NA/NB

This boot seals the hole where the shifter comes through the transmission tunnel. It will almost always be ripped on cars older than 4-5 years. When ripped, it will allow heat and noise to come up through shifter area. You will likely have to replace the small shifter boot at same time.

Mazda part NA01-64-481B, fits all NA and NB models including the Mazdaspeed.
