Gain up to 10 rear-wheel horsepower with an SLP high-flow air-box lid for your Camaro SS, Z28, Trans Am, Formula or Firehawk . This bolt-on unit eliminates the restrictive stock baffles and resonator assembly, significantly improving air flow to the throttle body on your LS1 engine. Use our high-performance air filter (Part #25012) for up to 5 additional horsepower.

NEW! All lids are now hot-stamped with a contrasting white SLP logo.
