Will The Exhaust Insulation Jacket Age After Long-term Use? How Often Should It Be Replaced?

Exhaust Insulation Jacket will age with prolonged use. They're often exposed to high temperatures and come into contact with oil, dirt, and moisture. Over time, the surface material becomes brittle, the internal insulation loses its effectiveness, and some may even crack or peel.
However, there's no fixed replacement schedule; it depends on usage. For family cars with good driving conditions, an annual inspection is sufficient. If the Exhaust Insulation Jacket show visible cracks, feel hard to the touch, or you hear them loosening while driving, they need to be replaced promptly.
Vehicles that frequently travel long distances, haul heavy loads, or operate in dusty, humid environments will experience faster aging. It's recommended to inspect them every six months. If signs of aging appear, do not delay replacement to avoid disrupting the vehicle's normal use or even creating safety hazards.
