A manifold’s job is pretty straightforward. It's basically a network of pipes, and it manages the flow of gases—either air and fuel into the engine (that's the intake manifold) or exhaust gases out of the engine (that’s the exhaust manifold). It distributes those gases evenly to all the cylinders so everything runs smoothly. It also has mounting points for things like your throttle body or exhaust connections. Think of it as a central hub for either getting air and fuel where it needs to be to make power, or for getting the waste gases away from the engine. The intake manifold connects directly to the engine's cylinders and receives air and fuel from the air filter and fuel injectors. The exhaust manifold collects those burned gases from the cylinders and sends them through the exhaust system—muffler, catalytic converter, and so on. It's a critical part of both the air intake and exhaust processes. A healthy manifold is super important for engine performance and efficiency. If it’s cracked or leaking, you’ll notice a loss of power, rough idling, and potentially even a check engine light. A leak in the exhaust manifold can let harmful gases into the cabin, which isn’t good at all. It acts like a shield, keeping those combustion byproducts safely contained and directed out of the vehicle. If it’s not working right, it can mess with your fuel economy and even damage other engine components over time. You’ll notice if it’s cracked – usually by a hissing sound or soot around the connections. We carry a pretty good selection of manifolds, if you’re interested.
