Because I can read a manual and understand how my engine's ECU operates, and because my CEL is STILL not on after over a week of driving and neither is Swiftoy's months after his similiar mod.
Don't know what the hp gain is, but I do know my throttle lag problem is virtually gone now. For what this mod cost ($0) its is well worth it. As I said, untill someone makes a CAI or SRI for our cars, this is the next best thing.
This pic illustrates my point (photo credit: SWIFTOY)...
This is a photo of the inside of the air box. The small opening (labeled "1") is the only air intake source when IAC valve #3 is closed. On the stock set-up the only time IAC valve #3 opens and allows air through the large air intake opening (labeled “2) is when the when the engine speed is more than 3,200 rpm and the opening angle of the throttle valve is more than 30 degrees.
With this mod, the large air intake (“2") is open at all times allowing for at least 4 times more air flow without any delays from the ECU to sense engine speed and throttle position, then trigger VSV #3 to finally open IAC valve #3. Now, how can this mod result in anything but a performance improvement to at least some degree?
