3000 Pipe Grommet Replacement - DIY Neoprene Washers

The rubber grommets/insulators on the 3000 pipe (upper intake pipe) deteriorate over time, becoming worn, cracked, or missing entirely, which can cause vibration, rattling, or poor sealing of the pipe mounting points.

Original rubber grommets on the 3000 pipe degrade after 30+ years of heat cycling and age, and Toyota replacement grommets are difficult to source.
