SLP High Flow Air Box Lid – 1998-1999 Camaro & Firebird (5.7L LS1) – 21044

Our Air-box Lids for 1998-1999 V8 Camaros and Firebirds are the perfect easy way to gain up to 12 horsepower! The bolt-on unit eliminates the restrictive stock baffles and resonator assembly, in turn significantly improving air flow to the throttle body. The lids are hot-stamped with a white SLP logo, and can be used with our high-performance air filter (PN:25010B) for up to 5 additional horsepower! Note: Not approved for sale or use in the state of California or other states that require a CARB E.O. # (Executive Order Number).
