leaking intake on 5.3

[chevyhome]

Would anyone know a aluminum replacement intake manifold for the 5.3 V-8. Are the LS1 or LS6 intakes compatable?

If you change out to an LS1 style or compatible your Air Flow is gonna be different and your calibrations in your pcm are going to need changes. If it's just a dd truck, then get another stock intake manifold. If it's a performance truck, then check out the FAST intake setup, check out Speed Engineering for that.

Oh BTW, if you swap out to a better flowing intake manifold you will not take full advantage of it unless you are forced induction.
