Air-Box Lid 98-99 V8 GM F-Body

The SLP Performance Air-Box Lid for 1998–1999 GM F-Body V8 models is a direct-fit intake manifold cover designed to enhance cold air induction for fourth-generation Camaros and Firebirds equipped with the 5.7L V8 powerplant. This component addresses a critical gap in OEM airflow dynamics by replacing the restrictive factory air-box lid, allowing cooler ambient air to reach the engine's intake tract more efficiently.

Built for enthusiasts serious about extracting genuine performance gains without forced induction, the SLP air-box lid is a bolt-on foundation piece in any street or strip-focused modification strategy. The rigid composite construction resists warping and maintains structural integrity through thermal cycling, which is critical for reliable street and track use where engine bay temperatures can rise rapidly.

F-Body V8 owners preparing for cam, heads, or supercharger upgrades will find this air-box lid an essential early-stage modification. Its design allows for improved cold air induction, contributing to lower manifold air temperatures (MAT) under sustained load, making it a valuable addition for performance-focused drivers.
