Hello good I have a 2000i8v115CV Renault Laguna of 1995 gasoline and cold and a bit hot and according to the macanic can be the spark plugs and also that these cars have to be the sullas, which indicate the engine plate. That is an EIQUEM C52LS. It has to be this one or it could be another of the same equivalence. According to the mechanic, if not, they could give problems. Thank you very much
