Automotive block off plates are components used to seal or block off openings or passages in various systems within a vehicle. They are commonly used for a variety of purposes, including performance modifications, emissions control, and maintenance. Here's an overview of automotive block off plates:
Types of Block Off Plates: EGR Block Off Plate:
Used to block off or disable the exhaust gas recirculation (EGR) system. EGR block off plates prevent exhaust gases from being recirculated back into the engine's intake manifold, which may be desired for performance reasons or to eliminate potential issues with the EGR system. Air Injection Block Off Plate:
Air injection block off plates are installed to block off the air injection ports in the exhaust system. This prevents fresh air from being injected into the exhaust system, which may be done to disable the air injection system or for performance modifications. PCV Block Off Plate:
PCV (positive crankcase ventilation) block off plates are used to block off the PCV system, which is responsible for venting crankcase gases back into the engine intake for combustion. Blocking off the PCV system may be done for performance reasons or to diagnose certain engine issues. Turbo Block Off Plate:
Turbo block off plates are used in turbocharged engines to block off or seal openings in the intake or exhaust system. These plates may be used during maintenance or repair procedures, or as part of a turbocharger upgrade or modification. Throttle Body Block Off Plate:
Throttle body block off plates are used to seal or block off the throttle body opening in the intake manifold. This may be done for diagnostic purposes, during engine testing, or as part of a performance modification.
