My car is 20k driven and i am quite satisfied with it, its my daily drive and its on petrol. the car has enough power to run through the city but the bad part is the real power lies above 5k rpm and that feels a bit too uncomfortable. also the power is not always available when you want it and you need to down shift usually .
Question is. How can i improve the performance , i have heard adding plugs/intakes/exhausts etc will make difference .
P.s "NO! no information is available on corolla specific performance related issue i have already searched the forums quite a lot"
