efi tune up 1.2...

there are some disadvantage connecting air filter directly to the throttle body... most obvious one is that it sucks hot air into the engine... as everyone knows, cold air yield more horsepower...

i did made a trip to local exhaust shop see if they can make a stainless steel piping extending the air filter to the area behind the headlamp... i was quoted Rm1xx...

hence i decided to copy cipan's idea of using flexible cold air intake hose as RAM pipe... unfortunately the cold air intake hose i'm selling isnt big enough to fit either the throttle body or the air filter... i'll need around 3 inch diameter hose... so, here it is....



the hose is same size with the air filter... took quite some time to squeeze the hose into the air filter... meanwhile on the throttle body side, the hose is a little larger than the throttle body outer diameter... despite not being the suitable size, i forcefully clamped the hose to the throttle body seal-tight...



improvement can be felt especially at low end rpm/speed... less laggy in throttle response... though i still miss the maniac sound of the open pod air filter directly connected to the throttle body...
