Breathers

Breathers are a part of your vehicles emission system. Breathers allow air movement between the atmosphere and the component it is installed in and relieves heat in the engine to increase performance.

How is it Made?

  • Most are a block or square of media material that is cut or formed.

Why Does it Fail?

  • Like most filters, type of duty impacts life or failure.
  • They can become clogged and need to changed 12 months or 12,000 miles.

What are the Symptoms of Failure?

  • Rough idle.
  • Tough starting.

  • Check engine light.

What are the Implications of Failure?
