Mazdaspeed Port Injection Block Off Plates – JMF, Damond & CorkSport
Running an aftermarket intake manifold or port injection-ready setup, but not ready to run port injection yet? The GGP Mazdaspeed Port Injection Block Off Plates are designed to seal off unused port injection openings while adding a clean finished look to your engine bay.
These block off plates are a simple solution for Mazdaspeed3 and Mazdaspeed6 owners using compatible JMF, Damond, or CorkSport port injection-style intake manifold setups. They allow you to keep your build clean and sealed while leaving room to upgrade to port injection later.
Whether you are still building your fuel system, waiting on tuning, or just want the look of a port injection-ready manifold without running injectors yet, these plates help finish the setup properly.
