intake, exhaust, ignition, fuel management

drop in air filter will help a lot due to higher flow of air

exhaust, if u wan to b silent, add more mid box, use s-flow muffler to gain more back pressure for yr auto gearbox since u;re n/a engine

change a set of iridium plugs is more than enough

fuel management, emanage ?

n also, take out everything unnecessary such as spare tyres if u always travel short distance
