Blower Manifold Spacer 4in - Polished

The Blower Manifold Spacer 4in - Polished from THE BLOWER SHOP is a precision intake manifold spacer designed for supercharged and turbocharged engines seeking optimal boost distribution and cooler charge air temperatures. This component is essential for those looking to enhance their engine's performance, particularly in high-horsepower street engines or competition platforms.

This 4-inch spacer creates thermal separation between the blower manifold and cylinder head, effectively reducing heat soak in the intake charge while improving volumetric efficiency. The polished finish not only enhances durability and appearance but also serves as a functional heat barrier. The design is built to withstand sustained boost pressures and thermal cycling, ensuring consistent performance across varying ambient conditions.

Engine builders, tuners, and serious enthusiasts operating Chevy big-block, LS, or similar displacement platforms will benefit most from this spacer. Its flat-face gasket surfaces maintain tight sealing integrity, which is critical for boost control and fuel calibration accuracy. This manifold spacer addresses one of the most overlooked variables in forced-induction tuning: manifold temperature control and even fuel distribution across all cylinders.
