What does the air injection hose do?New air injection hose Hamilton

Inside the exhausts of modern vehicles, a system exists that reduces harmful emissions. This results in a significantly reduced amount of pollution leaving your car. It also means that some of these gasses can be recirculated into the engine via the EGR system.

The air injection hose (or exhaust hose) is an important part of the emission control systems on most cars. As its name suggests, the hose introduces air into the exhaust. This helps to allow for the exhaust fumes to be converted into CO2.

The air injection hose is usually made out of plastic or rubber and is exposed to very high temperatures. This means that it is prone to wearing out over time. If the hose fails, you may notice problems relating to your exhaust emissions and engine running performance.
