Aslamualaykum , Brother u can use Suzuki genuine or after market filter also like Leppon (Malasian made) is also a good choice and it's good quality in cheap price, and where as Spark Plugs are concerned you can get NGK or Denso Spark Plugs but try to use the model which is recommended by a Company mean to say e.g if your Car has NGK model no 123 and on the other hand Denso has the same spec with model code Denso 345 , you can use any one of them , but try to get the genuine one whether it's made in Japan , Malaysia or Indonesia no prob.
