Intake Spacers, Adapters & Gaskets

Optimize intake manifold volume, reduce critical intake air temperatures (IATs), and ensure a perfect vacuum seal with high-performance intake spacers, carburetor adapters, and heavy-duty intake gaskets. Every component between your throttle body, intake manifold, and cylinder head plays a crucial role in overall engine performance. Factory gaskets and thin metal spacers are prone to heat soak, allowing radiant engine block temperatures to transfer directly into your intake tract. This super-heats incoming air, reducing air density and costing your engine vital horsepower.

Upgrading to a thermal phenolic intake spacer or precision-machined plenum spacer physically lifts the manifold off the hot cylinder head or increases the internal volume of the intake plenum—enhancing top-end power, airflow efficiency, and torque on high-RPM and forced-induction applications. For custom engine builds and EFI conversions, carburetor adapters allow you to mate specific carburetors (like 4150/4160 styles) to mismatched intake manifolds with precision. To seal it all together, high-performance thermal polymer composite gaskets and multi-layer steel (MLS) intake gaskets provide an impenetrable, reusable seal that resists extreme under-hood temperatures, high boost pressures, and chemical breakdown without the need for messy liquid sealants.
