Block Off Plates & Engine Plug Plates

Block off plates seal unused ports, openings, and passages on the engine block, intake manifold, and cylinder head. Whether you're deleting emissions equipment, capping unused coolant ports, or sealing off secondary air injection passages, a machined block off plate provides a clean, leak-free seal.

OneFastShop carries block off plates including billet aluminum and stainless steel block off plates, EGR delete plates, SAI block off plates, coolant port caps, intake manifold plugs, and engine-specific plug plates for popular performance platforms.

Every block off plate at OneFastShop ships brand-new with manufacturer backing. Whether you're cleaning up the engine bay on a track build, deleting unused factory hardware, or sealing ports during an engine swap, OneFastShop has the right plate. Shop the full block off plates collection today.
