This hose connects the secondary air pump to the catalytic converter. Basically, it delivers air into the exhaust stream. That air isn't for power, it’s more like a helper for the catalytic converter, helping it get up to operating temperature quickly and burn off any excess hydrocarbons – unburnt fuel – especially when you first start the car. It's a fairly simple part, just a rubber hose, but it has a specific job. Think of your catalytic converter as needing a good, hot start to work properly. The secondary air pump forces air in to kind of “jumpstart” that process. This hose is the delivery system for that air. It's part of the emissions system, so it’s designed to reduce harmful pollutants. You’ll find it connected to both the air pump itself, usually somewhere near the engine, and then running to a connection point on or near the catalytic converter underneath the car. It’s important because if this hose develops a leak, or cracks and breaks, the system won't work right. That can trigger a check engine light, and, more seriously, it can cause your car to fail an emissions test. A bad hose means the catalytic converter isn't getting the air it needs to do its job. The hose acts like a shield, keeping the air flowing where it’s supposed to. You’ll notice if it fails because the engine light will come on, and sometimes you might even hear a hissing sound near the engine. If you're looking to replace it, we carry a good selection of these at Fixparts Online, and it’s usually a pretty straightforward DIY job if you're comfortable working on cars.
