Offenhauser Performance Downdraft Intake Manifold 22R Dual Plane Weber Carb. Flange
One of the most important keys to building a performance engine is to have components that all match up and are designed to work together well. You can put the largest cam and carburetor on your engine but without a good flowing intake and exhaust you are just wasting money. This 22R intake manifold will work perfectly to get you the most performance possible from your engine.
The dual plane design of this manifold provides un-matched low end torque for low RPM applications. This manifold is equipped with a Weber carburetor flange so you can bolt your performance carburetor on the manifold without having to use any adapters. This manifold has all the same vacuum and sensor ports as your stock manifold so you don't have to worry about adapting different fittings together to get all your vacuum lines and temp sensors hooked back up!
This manifold is designed to use a rubber style thermostat gasket. There are a few other upgrades available for this manifold so take a minute to browse through the parts below to see if you will need any of them for your application. If you have any questions please contact one of our sales reps to help you determine what parts you may or may not need.
