sir u can put bosch 4-tip platinum plugs in it.wud cost u 250rs per piece. get 3 installed.
secondly u can get ur exhaust system done.im not 100% sure if its works but theoratically,it shud.get the diameter of ur exhaust pipe increased.the original piping has a diameter on 1.25" .increase it to 2".
then u can put air-intake,but that might bring the fuel economy down.if ur using cng,this setup is not recomemded.
u can also get a mixture of petrol nd highoctane to get increased power.
