This hose connects the air intake system to the throttle body. Basically, it's a pathway for clean air to get into the engine so it can burn fuel and make power. It needs to be flexible enough to handle engine movement but strong enough to maintain suction. Sometimes these hoses have a few different functions depending on the vehicle – some include a breather function, relieving crankcase pressure. Think of it as a vital link in the breathing system of your engine. The throttle body controls how much air gets in, and this hose makes sure that air gets there reliably. It’s part of what helps regulate your engine’s performance, fuel efficiency, and even how smoothly it idles. It connects to the air filter housing and the throttle body itself, so it’s right at the heart of things. A cracked, brittle, or leaking throttle body hose can really mess things up. You’ll notice if it’s bad – probably with rough idling, a check engine light, or a loss of power. The engine won’t be getting the right amount of air, so it’ll run poorly. It acts like a shield against outside contaminants, and if it’s compromised, dirt and debris can get into the engine. It's not something you want to ignore. We carry a good selection of these, and you can often find exactly what you need on Fixparts Online, too. Replacing it is usually a fairly straightforward job, and a new hose can make a big difference in how your engine runs. Invest in longevity: Hose (MPN A0020945282) comes with a 12-month warranty!
