Angled Carb Ring

The FIVESTAR Angled Carb Ring is a 0.75-inch aluminum air cleaner spacer designed to integrate with 5-1/8-inch carburetor flanges in cowl induction cold air intake systems. This angled spacer modifies the plenum geometry between the carburetor and air cleaner assembly, allowing builders to optimize intake manifold clearance and airflow trajectory on carbureted engine builds where hood height and engine bay packaging present real constraints.

Constructed from aluminum in a natural finish, the ring measures 5.55 inches across and weighs 0.21 pounds—light enough to have zero impact on engine balance while maintaining structural rigidity under normal intake vacuum and atmospheric pressure. The angled design distinguishes this spacer from flat rings; the angular transition manages air velocity into the carburetor bowl while reducing turbulence at the fuel inlet. This geometry becomes critical when using cowl induction systems, where air velocity and intake angle directly influence mixture distribution and off-idle response. The 5-1/8-inch flange compatibility confirms fitment with standard Holley, Edelbrock, and many Demon carburetor applications common in street and bracket racing builds.

Buyers installing custom cold air intake systems—particularly those retrofitting cowl hoods on classic American muscle cars or small-block V8 restorations—rely on spacer rings like this to bridge height gaps and correct intake angles without sacrificing fuel atomization. The angled profile also serves builders tuning for low-end torque response, as the modified air path can influence carburetor signal characteristics. Installation requires only four fasteners through existing bolt holes on the carburetor flange and air cleaner base.
