There are 2 types. Drop in (replce the stock air filter element) and open pod (those mushroom type). Drop in can esily be DIY but open pod need some extra work such as piping, heatshield and CAI to work properly but it will give more pickup than drop in (if done correctly).

surbo? many who installed it would later uninstall it.... google for their reasons....

i surely have to do sth about mine.... 

it will be "reliable" if you change your ATF Fluid every 20,000km and remember to use only Genuine Proton ATF III fluid. And remember do not flush your gearbox as that will only shorten the gearbox lifespan. That is due to high pressure applied to force the left over fluid out from gearbox at the same time some oil seal might leaked.

I'm the one that doing this practise now.

Apek said spoilt only change arr? hahaha....apek is referring to mini minor kot? hahaha...

For spark plugs is depends on what type your're using. If normal plug is around 20K to 30K mileage, platinum is 60K-70K mileage, Iridium is about 150K-160K. The above figure is for your guideline only you can change it earlier or later if you're really sensitive on performance. If possible get an iridium spark plug for more long lasting, Denso is around RM160 (0.4mm tip), NGK is RM130 (0.6mm tip), Volker is RM220 (0.5 or 0.6mm tip).

Meanwhile ATF+labour will probably cost you RM120~RM130 in Proton SC.

i'm using 196/60/15 with APM performax shocker + standard spring. Handling is like VAN!!!.

persona is a good choice indeed. I own Waja and Gen2 and i like both of them that's why i brought it hehehehehe....

Waja handling are pretty good but mine waja are not performing as it suppose to be.
