Chrysler Small Block Carbureted Dual Plane Air Gap Aluminum Intake Manifold - Black

• Compatible with "LA" and "Magnum" series engines

• Requires the use of 1975 or earlier water neck

TSP's dual-plane air gap intake manifold for the small block Mopar is ideal for high-performance applications. Its improved design is complimented by an open area under the plenum. This feature ensures less heat transfer from the engine, meaning the air/fuel charge will be cooler and produce more power and torque. Producing power and torque comparable to single-plane manifolds, it retains the drivability and throttle response like other dual-planes and performs best between 1,500 and 6,500 rpm. It is cast from lightweight aluminum and features a relatively low profile for great hood clearance. Additional provisions include nitrous bosses, a rear water crossover with additional ports, and a square bore carburetor flange.

What engines is this intake manifold compatible with?
This intake manifold is designed for Chrysler Small Block V8 applications, including 318, 340, and 360 combinations, and it is intended to work with both LA and Magnum series engines.

Will this intake fit a 318, 340, or 360 Mopar?
Yes, this intake is designed for Chrysler Small Block V8 combinations including 318, 340, and 360 applications.

What type of carburetor does this intake support?
This intake uses a 4150 square bore carburetor flange and is built for single 4-barrel carbureted applications.

What RPM range is this intake designed for?
This dual plane intake is designed to perform from 1,500-6,500 RPM, making it a strong choice for performance street and street/strip use.

What is the benefit of an air gap intake design?
The air gap design creates an open space under the plenum to reduce heat transfer from the engine, helping keep the air/fuel charge cooler for improved power and torque.

How does this compare to a standard dual-plane intake?
Compared to a standard dual-plane intake, this air gap design offers improved mid-range and top-end performance while still maintaining good throttle response and street manners.

What type of intake manifold is this?
This is a dual plane aluminum intake manifold with an air gap design, built to improve low-end and mid-range performance while maintaining good drivability.

Will this intake clear a stock hood?
It features a relatively low-profile design to help with hood clearance, with a front height of 4.900 in., center height of 5.350 in., rear height of 5.800 in..

What material is this intake made from?
It is cast from lightweight aluminum, which helps reduce weight and improve heat dissipation.

Is this a direct bolt-on intake manifold?
In most cases, this intake is designed as a direct-fit manifold for compatible Chrysler Small Block V8 applications, though proper gaskets, carburetor setup, and supporting components are still recommended during installation.

Are there any installation notes I should know about?
Yes, this intake is designed for LA and Magnum series engines and requires the use of a 1975 or earlier water neck.

Will this intake improve throttle response on my Chrysler Small Block?
Yes, the manifold design helps improve airflow and mixture distribution, which can translate to better throttle response and more consistent power delivery.

Is this a good upgrade from a stock intake?
Yes, this intake is a solid upgrade for compatible Chrysler Small Block V8 builds that need improved airflow, better drivability, and stronger performance across the usable RPM range.

Does the black finish affect performance?
No, the black finish does not change the manifold's performance characteristics—it primarily changes appearance and adds a more aggressive engine-bay look.

Is the black finish durable for long-term use?
Yes, the black finish is designed for durability and corrosion resistance when properly maintained.
