I bought those injectors ( venom ) over a year ago and then Ash said he didnt care for them so I got what he recomended . Now a year later my z is in a million pieces waiting on a long block and yesterday my Tahoe blows a head gasket filling my pan with water .... so today i sit here with no ride looking for things to sell to keep up and i run across these injectors (nib) and offer them for $199 , half of what i paid . I see people here that have a set and one or two won"t ohm out so they are looking for some. these are new with no harm intended . If you do not like what i am selling or had a bad experience with them then please move on . Next !
