We present a search for excited neutrinos and electrons using all data collected by the HI experiment at HERA at a center-of-mass energy of 320 GeV with an integrated luminosity of up to 435 pb-1. No evidence for excited neutrino or electron production is found. Mass dependent exclusion limits are determined for the ratio of the coupling to the compositeness scale, f/Λ. These limits greatly extend the excluded region to higher masses than has been possible in previous searches.
