What does this do?
 

Im wondering what the exact function of the piece i have circled is?

Air Boost Valve (Starting Valve), It just gives more air when youre cranking the engine during startup, so you don't need to touch the gas pedal to open the butterfly up to let more air in.

I've seen many intakes without it, im thinking of getting rid of it, what do you think?

honda put it there for a reason... unless you have an engineering degree and decide that honda doesn't know **** ... I'd leave it alone....

then again I enjoy a nice stock car for a reason. I trust them big brains at honda

brett, alot of people from honda-tech remove it,
honestly maybe your b16 was an automatic...and thats why its there.

alot of jdm importers are pulling these motors out of the integra xsi, which ALOT of them are automatic, then they are re-mating them with a bseries tranny.....

have you raced any other b16a?, because if it is an auto, then the cams are def, less HP, compared to the manual counterparts.


look at colvins first ZC or the current one in his ef, its an automatic, jdm importers are running out of the old shcool motors for our cars, and we are getting stuck with the automatic motors.
the ZC I ordered also is a auto, so I am going to be busy swapping over cams/intake manifold..

yeah, it think it will be coming out, i've already had it off and it makes no difference to how the car runs. I know that honda put it there for a reason but, i don't need the undue complexity

honda's brains are smart but for street cars they design them for fuel economy in place of raw hp... i put a small resistor in place of a sensor on the car and got a noticeably better revving motor

can u do it on mine:blush:

i can do a lot of things

so... can u?

yes i "can"

rick was that the eacv?

i'm really not at liberty to say... and mostly i have no idea what its called....

Rick aren't you talking about the idle air control valve from that ebay based thread of a few weeks ago?

shhhhhhhhhhhh

hahaha maybe

i soldered a few resistors together to get a better over all resistance though

that is same stuff no?, at the back of the intake manifold,

eacv, take it off the car will run richer, and the resistors, so you dont shoot any codes?

funny im running a resister right now in my throttle position sensor (its broken) gives me an ecu code but not a check engine light? hope to have a replacement by the weekend
