- change ur intake manifold to a custom made polished manifold from both sides. inner and outer side must b chrome polished. or it shud be made from stainless steel.
then u must install performance headers(usually known as the custom exhaust manifold). This also must b of stainless steel and get a free flow piping frm the headers to the tail and after that install a gud quality muffler at the last. Free flow piping means no dholki from engine to tha tail pipe. ok.
now cum 2 the spark plugs. u just get DENSO Platinum or Iridium plugs wid single tip.... there is no need to get BOSCH Super 4, if ur ignition system is stock. if u r going to change the ignition system with a MSD one, then u need the bosh super 4 spark plugs with 4 tips or any higher quality. but still u don need that.
NOW U INSTALL ONE OF THE AIR FILTERS LIKE SHOWN IN THE PICTURE....
and after that get ur car tuned from a professional person. thats it....
according 2 ur wish, u will feel a great difference.......
here is the picture of MSD(Multiple Spark Discharge) Ignition system installed in a civic
the modification explained above is enough for a stock engine to give a great pick and shoot out.
I m myself an automobile technician, working in toyota dealership......

thanks
