4 corner steam kit?

OK.
I just block them off.
If I block them off with an interconnected hose the air will just rise into the hose.
But then it has nowhere to go....trapped again.

I think there are two schools of thought on the steam vents....some say do it, others say BS.
They make block offs too.

Same thing on the TBSS upgrade.
Some would say if you don't upgrade to at least a 90mm 4 bolt TB, you won't get enough air into the intake for the TBSS to work.
But others say it'll be fine with the 3 bolt. Only with a dyno tune can you really tell.

Early LS equipped trucks (like my 2000 Sierra that originally had a T code 5.3) had a factory 4 point steam tube assembly that all ran together instead of just tying the front two together underneath the intake. That early factory assembly hugged my valley plate pretty well if I remember correctly and would probably fit under the TBSS

I’m in the process of building a 5.3

View attachment 276120 I used the stock 4-corner steam vent, like mentioned above, underneath my TBSS intake, and it fit just fine.

This photo gives a better perspective, but it was before the TBSS intake.
