(a) ATF Cooler (Brand Hayden);
(

(d) Denso Iridium IK20 plugs;
(e) Air-Intake (80s device for fuel saver) - Ayam brand from Brothers Accessories;
(f) Custom made Capacitors which one affixed to the lighter wiring behind the dashboard and another mounted on the
Battery;
(g) Projector and HID from CSB-Pro Autolight (Subang USJ 1); and
(h) 16" rim with Continental MC5 195/55/16;
(i) Zenden 2 points front strut-bar;
(j) OEM Proton Preve steering with shift pedals (of course the shift pedal is not functioning; and
(k) front and rear camera with the displayed in the double-din screen; and

With the above the car is currently doing 10.5 to 11 km/litre (average) for town driving and 16 km/litre (average) on highway with Petron Ron 95 and TOTAL Fully Synthetic 5W-40 Engine Oil.
I am considering 4-2-1 extractor and to remove the cat converter but the pros and cons of these upgrades are not certainable yet.
