Cylinder Head Block Off Plates

UPDATE 2025: Now laser cut from ABS plastic instead of 3D printed!

The game changer you never knew you wanted. When removing your intake manifold or headers either in the car or on the stand, we usually stick rags into the ports to prevent FOD from entering the engine. The problem with this is, debris can still get in, or worse loose a rag. To solve this, we created custom cylinder head block off plates for your BMW engine. These thick, high quality block off plates are completely plug & play and will 100% protect anything from falling into your engine.
