Sprint Air Box Seal 2 3/4in-3in Stacks

The Sprint Air Box Seal 2 3/4in-3in Stacks by SEALS-IT is a precision intake manifold sealing component designed for high-performance engine builds and cold air intake modifications. As an experienced mechanic, you know that air box assemblies require reliable sealing to prevent vacuum leaks, boost loss, and unmetered air from compromising engine tuning. This seal addresses the critical gap between intake stacks and air box walls on performance applications where factory seals fail or aftermarket components demand custom solutions.

Built with durable elastomer construction, the Sprint Air Box Seal accommodates stack diameters from 2 3/4 inches to 3 inches, making it compatible with both carbureted and fuel-injected engine platforms. The seal's flexible design compresses to create an airtight interface without restricting air flow, a critical balance in performance intake systems where even minor leaks can cost horsepower and create lean-condition codes. Its compact profile—measuring just 0.65 inches in width—fits tight engine bay spaces without interfering with manifold geometry or adjacent components.

Builders working with custom sprint car stacks, drag racing intake manifolds, or upgraded cold air box assemblies will appreciate this seal's versatility across the 2 3/4-to-3-inch diameter range. Installation requires minimal modification—simply position the seal between your stack and air box housing, then secure your intake assembly using existing fasteners. This component is essential for anyone upgrading breathing components on carbureted engines or maintaining boost integrity on forced-induction platforms where every cubic foot per minute of air matters.
