Made from cast aluminum, the intake manifold is both durable and lightweight, reducing engine weight and contributing to improved engine performance. The intake is also finished with a high-temperature powder coat to protect against heat and corrosion.

By upgrading to this high-performance GM 3959594 SB Chevy intake manifold, you can expect an increase in both horsepower and torque, as well as improved throttle response and engine idle stability. Suitable for both street and track use, this intake is an excellent upgrade for those looking to optimize their classic Chevy's performance.
