This intake manifold spacer (part ) installs between your intake manifold and carburetor to increase plenum volume and improve air/fuel mixture distribution. Adding plenum depth changes the effective runner length of your induction system, typically shifting the torque curve lower in the RPM range for improved low-end and mid-range power. It is a budget-friendly induction upgrade that wakes up a mild street engine without major modifications.

Machined from a heat-resistant material that reduces fuel charge heating for denser air/fuel mixture entering the runners. The 4-hole design improves mixture distribution across all four carburetor barrels, reducing lean cylinders that cause hesitation and surge. CNC-cut to match standard Holley 4150 or Edelbrock AFB flange spacing with a precision gasket included for a leak-free seal. Approximately 1 inch of additional plenum depth.

Place the spacer between the intake manifold and carburetor with gaskets on both sides. Verify your throttle linkage clears the added height before tightening. You may need longer carburetor studs depending on the spacer thickness. No tuning changes are typically required after installation, though checking manifold vacuum is recommended to verify the seal.

Frequently Asked Questions

What thickness options are available for the INTAKE MANIFOLD SPACER on my intake manifold?

The INTAKE MANIFOLD SPACER is available in 1/2 inch to 1 inch thickness depending on your hood clearance and intake manifold setup. This carburetor spacer raises the carburetor to improve air-fuel mixture distribution across the intake plenum. The spacer material — typically phenolic or aluminum — affects heat transfer and fuel atomization characteristics.

Does the INTAKE MANIFOLD SPACER help reduce intake manifold heat soak on hot days?

Yes, the INTAKE MANIFOLD SPACER acts as a thermal barrier between the hot intake manifold and the carburetor when made from phenolic material. This carburetor spacer reduces fuel boiling and vapor lock issues by keeping the carburetor 20 to 40 degrees cooler. The open plenum design maintains airflow velocity while providing the thermal break.

Will the INTAKE MANIFOLD SPACER increase low-end torque or top-end horsepower on my V8?

The INTAKE MANIFOLD SPACER primarily improves mid-range torque by 5 to 10 lb-ft when using a 1-inch open spacer design. This carburetor spacer increases the effective plenum volume, which enhances cylinder filling at higher RPM. A 4-hole spacer design improves low-end torque while an open spacer favors top-end horsepower on most V8 engines.

What specific performance benefits does the INTAKE MANIFOLD SPACER offer for my vehicle?

The INTAKE MANIFOLD SPACER enhances your vehicle's air and fuel delivery system for improved power and efficiency. This performance part is engineered to OEM specifications or better using high-quality materials. Expect noticeable gains in throttle response and overall driving experience after installation.

Is the INTAKE MANIFOLD SPACER a direct bolt-on replacement for my factory component?

The INTAKE MANIFOLD SPACER is designed for direct fitment on your specific vehicle application without major modifications. This component uses factory mounting points and connections for a straightforward installation process. Basic hand tools and approximately 30 to 60 minutes are typically all that is needed.

Does the INTAKE MANIFOLD SPACER require any ECU tuning after I install it on my engine?

The INTAKE MANIFOLD SPACER typically does not require ECU tuning for basic bolt-on installations on stock or mildly modified engines. The engine's computer can compensate for small changes in airflow or fuel delivery within its learning parameters. A professional tune is recommended if you combine this with other significant engine modifications.
