The ceramic body may have an exterior surface that includes an outer surface and an inner surface interconnected to one another by at least a leading edge, a trailing edge, a tip facing edge and a base facing edge. The ceramic body may define a plurality of apertures extending between the outer surface and the inner surface. The ceramic body may include a trailing first pin and a leading first pin. The trailing first pin and the leading first pin may extend away from the inner surface. The leading first pin may be spaced away from the trailing first pin and in closer proximity to the leading edge than the trailing first pin.
