EGR—the apparatus that we love to hate on our 280Z/280ZX. Virtually everyone wants to get rid of it, and everyone looks for non-EGR manifolds, but they are quite hard to find nowadays. So we came up with a solution—EGR block-off kit. Our kit includes a zinc plated EGR block-off plate, gasket, two bolts, and an allen plug. If you use stock exhaust manifold, you would need two allen plugs (we can sell additional one separately. $6/ea).
