Offenhauser Downdraft Intake Manifold

(Weber Flange / Single Plane)

One of the most important keys to building a performance engine is to have components that match up and are designed to work together in harmony. If you have an awesome cam and carburetor a good flowing intake will make sure you're getting the most benefit from those parts.

With a large open plenum and runners, our customized Offenhauser manifold will greatly outflow your stock Toyota manifold and supply your engine with enough airflow to support the power goals you're shooting for. The single plane design provides an excellent mid-range to upper RPM power without sacrificing low-end torque. The casting is designed with a Weber carburetor flange so you can bolt your performance carburetor straight to the manifold without the need for any adapters. All the same vacuum and sensor ports as your stock manifold are included. If you have plans in your build to not use any of those ports, see our plug kit listed below.

This manifold is designed to use a rubber style thermostat gasket, instead of the stock paper flat gasket.

We have many additional supporting upgrade parts available to work with this manifold which are listed below. Have a look to see if there is anything you're needing for your build before you're elbows deep! If you have any questions please contact one of our sales reps to help you determine what parts would work well for you.

NOTES: This manifold requires a 1981-1982 thermostat housing which is no longer available from Toyota. You can use the later style thermostat housing with our Thermostat Housing Adapter listed above. This manifold uses an 8 bolt bottom plate. If you do not have an 8 bolt plate on your manifold you will need to purchase our Water Plate Under Manifold listed above. This manifold does not allow clearance for the factory heater outlet. If keeping the heater, you will need to block the original supply on the head with the Pro Water Block Kit above and run heater supply from the water plate on the bottom of the manifold. If your plate does not have a hose barb to connect to, we would recommend our Water Plate Under Manifold listed above. You will need to purchase the Pro Water Block Plate Kit if removing or changing the location of the heater supply as outlined above.
