As the title says, stock spark plugs are worn out and my mechanic recommends to replace them. I have seen many threads here where people recommend Iridium or Platinum spark plugs. So which brand and model of Iridium or Platinum spark plug will suit the engine of my 2000 Model JDM ALTO VXR 660cc Automatic. Also should i change the cables too with spark plugs???? Need experts help here ...
Also, to increase the cars performance which stuff should i install in it?????
Thanks in advance you guys rock
