SLP High-Flow LS1 Air-Box Lid for 1998-1999 Chevrolet Camaro and Pontiac Firebird (21044)

$139.99

Fits 1998-1999 Chevrolet Camaro and Pontiac Firebird models (Base, Z28, SS, Formula, and Trans Am) equipped with the LS1 engine.

The SLP High-Flow Air-Box Lid (MPN 21044) is a direct-fit replacement for the restrictive factory air intake lid. Designed by performance specialists, this lid eliminates the baffled, airflow-disrupting design of the original equipment to provide a smoother, more direct path to the throttle body. By reducing intake turbulence, your LS1 engine can breathe more efficiently, supporting better induction performance and throttle response.

  • Direct Bolt-On: Installs easily using factory mounting locations with no permanent vehicle modifications required.
  • Improved Induction: Replaces the restrictive OEM lid to optimize airflow into the intake manifold.
  • OEM Compatibility: Works seamlessly with factory air filters and high-performance drop-in replacements.
  • Durable Construction: Engineered to withstand engine bay heat while maintaining a secure seal.
  • Manufacturer Part Number: 21044
