yo, i've got a bb2 h23 and there's a part on the intake manifold which i have no clue what purpose it serves, basically id like to know. id also like to know if its possible to remove it, since ive seen pictures of h23's with it missing. check the pictures!

cold start valve.

don't need it. Ive started mine without it when it's -20*F

 

right on, thanks man.

don't suppose you know anywhere i can get a plate to bolt over the hole? probably best to just fabricate one, right?

 

they are out there.. my JDM h22 intake had a factory block-off plate...probably be quicker and easier to just make one tho.
