Sprint Air Box Seal Ext Lip 2-5/8in - 2-7/8in

The Sprint Air Box Seal Ext Lip 2-5/8in – 2-7/8in by SEALS-IT is a precision intake sealing component designed to eliminate unwanted air leaks at the air box junction. This extended lip seal addresses a common performance tuning challenge: factory air box connections often develop micro-gaps that allow unfiltered ambient air to bypass your intake system, compromising fuel mixture accuracy and engine efficiency.

Constructed by SEALS-IT, a recognized manufacturer of automotive sealing solutions, this extended lip seal features a flexible design that accommodates the 2-5/8in to 2-7/8in diameter range, making it adaptable to slight variations in air box and intake manifold dimensions common across different model years and engine configurations. The extruded lip profile creates a positive mechanical seal rather than relying on compression alone, preventing vibration-induced separation that can occur under sustained throttle application or high engine loads.

This seal proves particularly valuable for tuners, enthusiasts, and mechanics performing cold-air intake upgrades, fuel system modifications, or engine management recalibration where intake air accuracy directly impacts dyno results and driving performance. Its lightweight design integrates seamlessly without adding unnecessary weight or complexity to your intake track.
