The intake manifold is the platform that directs air/fuel mixture from the carburetor or throttle body fuel injection to the cylinders. For OEM quality replacements, we offer a selection of application-specific intake manifolds from Dorman. If you're looking for performance intake manifolds, our selection of Edelbrock, Holley and Weiand parts are designed to enhance throttle response and widen the engine's torque curve. Use our parts lookup tool to find out which intake manifolds are right for your vehicle and see valuable warranty information - and don't forget the gaskets for installation.
Performance intake manifolds are designed with several features that enhance horsepower, torque and throttle response. They're usually made from aluminum for lighter weight (10 lb vs 50 or 80 lb for an OEM cast-iron unit). Their runners to each cylinder are smoother with bigger ports for better flow and efficiency, and the higher rise helps the fuel/air mixture develop more velocity before it enters the cylinders. In many cases, when an intake manifold, carburetor and camshaft for a given engine are from the same manufacturer, they're designed to work together to optimize performance. Depending on your engine's torque curve, you can opt for a single or dual plenum manifold that's set up for either a spreadbore or squarebore 4-barrel carburetor.
Thinking about upgrading your ride with a performance intake manifold? We've got what you need, with a great selection of intake manifolds from brands like Edelbrock, Holley and Weiand. Don't forget to get the gaskets you need for the job, and you might want to consider replacing the bolts as well.
