I remember reading some where there is a stock Air Flow Meter, that is actually bigger than the stock V6 3.0 one. Is this true and do you have to adjust it to get the correct air to fuel ration once installed. I’m looking to open the whole intake system correctly. This would start with a bigger Air Flow Meter, Bigger piping from the air flow meter to a bigger bore throttle body, and a ported and polished intake manifold. Then I would be looking into a possible header that has proven to work. I know with the whole intake and exhaust system the gain in power should be no more than 10hp. Max.

 

search feature works great...

try using it to search for the camry AFM swap...

negligible difference, but its something else for the "cool factor"...

 

1st, calculate the total wide open air flow requirement of the engine at redline + 50% (for margin-error/safety considerations)
2nd, calculate the air flow capability of the intake system.
3rd, calculate the flow capability of both the throttle body and the air flow meter.

As is apparent, you'll have to do some measuring and such in order to reach your answer.

 

Or on the other hand... I'm suggesting you are grasping at straws....

 

So another question why didn’t Toyota engineer the Air Flow Meter box round? I would think the square design with create a ton of turbulence.

 

A round passage would make designing the flap/vane mechanism inside more difficult.

 

Yep, round would be quite tricky to design. There isn't anything wrong with rectangular.
