When I bought my 06 CDI, the PO made the remark that, compared to the 05, there was an updated injector bolt design that made the 06 less susceptible to black death. Does anyone know for certain whether or not this is the case? I'd be glad to compare photos with someone who has an 05 if there's any interest.
