I tried searching for this but couldnt find it anywhere.. How much more air does the d16z6 intake manifold flow over what the d15b7 one does..

Also does anyone have pics of the 2 of them.. I remember seeing a post about this a while ago but cant seem to find it for the life of me.. Thanks

 

I know someone has pics..

Better yet is there any way to tell the difference between a d-series non-vtec and vtec one.. Like distinct markings or something.. Let me know.. Thanks..

 

i know the y series...

the d16y7 manifold is like a claw with the throttle body mounted facing upward, no real plenum, and the filter is positioned on top of it

while the y8 manifold is the more common type with the side mounted TB and a plenum with runners..

dont know the d15 intakes tho...

 

I have seen pics of the y8 manifold but I think the one that I got from my friend is suppose to be a z6 one.. Im just wondering if there is a difference between the d15b7 and d16z6 manifolds..
