The 4in Single Inlet Air Plenum by SPECTRE is a precision intake manifold component designed to enhance airflow distribution in high-performance engine builds. This plenum chamber acts as a crucial transition point between the intake runner and fuel-injected engine bay, consolidating incoming air before directing it to individual cylinder ports. It is suitable for various applications, including street machines, carbureted classics, and modern fuel-injected platforms.
The single inlet design minimizes turbulence and resonance, allowing for better velocity maintenance while preventing high-frequency reversion. Its construction is designed to withstand manifold heat cycles and fuel system pressures, ensuring reliability for carbureted, TPI, or modern EFI fuel delivery systems. This plenum is engineered to optimize volumetric efficiency across your target RPM band.
Ideal for small-block Chevy, Ford, and Mopar engine swaps, this plenum addresses the limitations of factory intake manifolds that may be restrictive or incompatible with performance cylinder head ports. Its single inlet configuration simplifies installation in tight engine compartments, making it a versatile choice for performance enthusiasts.
