Blower Manifold Spacer 4in - Polished

The Blower Manifold Spacer 4in - Polished from THE BLOWER SHOP (Part Number 5024) is a precision aluminum spacer engineered for supercharger applications requiring vertical separation between the blower unit and intake manifold. This 4-inch tall polished aluminum spacer is compatible with 6-71 through 14-71 displacement superchargers, making it a versatile choice for builders working across a wide range of forced-induction engine platforms.

Constructed from aluminum, the spacer provides both weight efficiency and thermal isolation between the supercharger and manifold—critical factors in managing underhood temperatures during sustained boost. The polished finish offers corrosion resistance and a professional appearance on visible engine components. At 30.85 lbs and measuring 14 x 8 x 26.5 inches, this spacer is substantial enough to handle the rigors of high-displacement applications while maintaining dimensional accuracy critical for proper blower mounting and belt alignment. The 4-inch height is engineered to optimize hood clearance on most modern and vintage builds while preserving intake tract geometry.

Engine builders and automotive enthusiasts preparing 6-71, 8-71, 10-71, 12-71, or 14-71 supercharger installations depend on manifold spacers to ensure proper component fitment, maintain correct pulley and belt angles, and protect the intake manifold from direct supercharger heat transfer. This spacer is essential for anyone building or upgrading a blower-equipped engine and requiring precise vertical spacing without compromising structural integrity or thermal management.
