I bought the wagon R New K series version on May 2010. now I almost complete 13k KMS. its seems to be too noisy in his engine even worser than the Diesel engine. I checked with the service centre they comment all the K series engines are like that only., even I checked almost more than 20 cars in same engine everything are very noisy. it seems to be a lorry driven. I humble request dont go for K series engine. if you a doubt pl visit my vehicle(9092020351). there is no proper response so far from martuti side also.
