NBI LS Exhaust Port Covers

NBI Exhaust Port Covers

Stop relying on painter’s tape to keep dirt and moisture out of your cylinder heads.

Our NBI Exhaust Port Covers are designed to seal the exhaust ports during engine storage, transport, assembly, or shop work. Each set includes the hardware and O-rings needed to create a secure seal and help protect the cylinder heads from dirt, moisture, dust, and debris.

The O-ring design provides a watertight seal around the exhaust ports, making these covers a much cleaner and more reliable option than tape when storing or moving an engine.

For cylinder heads that already have O-rings installed in the exhaust ports, a flat cover option is available without O-ring grooves.
