Description
If you're running a carbureted or naturally aspirated LS engine without secondary exhaust ports, blocking off those unused openings prevents vacuum leaks and maintains proper air-fuel ratios under boost or high-RPM conditions. The Moroso block-off plates seal exhaust ports cleanly, eliminating the need for improvised solutions that compromise reliability. A simple bolt-on installation means you can address this critical detail without tearing into your engine bay.
