STM Head Port Block Off Plate for Evo X 4B11
STM Evo X head port head block off plates are designed to completely seal off your intake or exhaust ports while you have the manifolds off.
Whether you're building your motor or swapping out parts, this will keep dust and debris (not to mention creatures) out of the ports and also makes your fresh build much more photogenic compared to bunched up paper towels when it comes time to show it off! Also great for shipping engines.
