i may have read wrong but i thought they said this piece was tricking the ecu into thinking it was getting more condense cold air. well if it has to trick it into thinking that, its not actually getting it (or this piece wouldnt be needed). so how is that not causing a rich mixture. yah if it was actually getting the colder denser air it would need the extra fuel for the right mixture....but its tricking it into thinking that colder denser air is there....so its really not there, but yet getting more fuel.....did i read wrong here?
