cold air intake...

many sifoo say cold air can help the car move about better... why arr??... simple theory lo... this is also why u feel ur car more powerful during night time compare to hot sunny afternoon....

cold air are more condensed than hot air... condensed air means got many O2 molecul inside...
while combustion need O2 and fuel to burn, increasing O2 helps the fuel burn more efficiently....

so, i once again dived into the engine bay and made this to my airbox...



the stuff that wrap around the airbox is superlon... some kinda material that insulated the heat so the airbox wont get heated up easily....


as far as i know, older version saga iswara has an extra hose that connect the airbox to the side fender.... mine dont have... so, DIY one lo....



result was noticeable... as it is now sucking in colder air from outside of the car, pickup improved especially during hot afternoon....
