Note: This intake manifold is designed to bolt up to the heat box on your original exhaust manifold. Exhaust heat must be routed to the bottom of the intake to help keep the fuel droplets suspended in the air/fuel mixture, providing better cold weather performance and overall driveability.
If using split manifolds or exhaust headers, you must still supply heat to the bottom of intake using a heat box that you fabricate. This can be done by routing either exhaust heat or engine coolant to the bottom of the intake via copper or steel tubing.
