What Are Breather Hoses, And Why Are They Important?

The car performance largely depends on how your car engine performs. In the last decade, car engines have been upgraded to a great extent. They are now more powerful, do not overheat, and deliver fuel efficiency. Dozens of accessories play a vital role in improved engine performance. In this way, a vacuum and breather hose is one of the major engine components that help the engine perform better.

What exactly is a breather hose?

A breather hose acts as a vent Pipe. It allows the internal combustion engine to remove pressure and heat from the engine. This provides better combustion and lesser fuel consumption, leading to improved fuel economy and increased horsepower. In other terms, the breather or vacuum hoses help the cars to obtain proper oxygen levels into the engine’s combustion chamber for lesser fuel consumption.

Where does the breather hose located in the car engine?

The vacuum and breather hose is usually located in the oil cap. However, the location of the breather hose depends on the type of car engine. If the breather hose blocks, the crankcase will pressurize and cause many problems like impurities such as water vapors and acids building up and contaminating the oil, causing increased engine wear possibility.

Replacing the breather hose will not take more than 15 minutes using the everyday tools. If you are not willing to replace your vacuum and breather hose own, then visit your local mechanic.

How do I know the breather hose is bad?

When the crankcase breather hose goes bad, it displays some symptoms that you need to notice, including oil leaks, high idle, and degrading engine performance.

Know the importance of timely replacements

The worn plastic or rubber hoses should be replaced immediately because the obstructions in the engine ventilation system can lead to increased pressure in the crankcase, ultimately leading to engine failure. Moreover, cracks in the pipe can result in the release of toxic gases into the environment. This will also let the air passes into the intake pipes, which will degrade the air-gasoline mixture, causing the engine to misfire. This may lead to rough idling or can even bring the car to a complete stop.


If the vacuum and breather hose shows any signs of wear and tear, then our strong recommendation is to replace the breather hose with the new one. This will help you avoid taking any risks and cause damage to your car engine as well as your car. Hence, whether it is a breather hose or a universal silicone coupler reducer hose, replace them immediately if you notice any wear and tear to ensure the engine performance doesn't get affected.
