I have 2 factory intakes that are identical to each other...they fit the 4.8 5.3 and 6.0, one came off a 04 silverado 5.3l and the other came off a 03 denali lq4 6.0, they are both identical as is any 4.8 motor. both in perfect condition, both come with a hardly used air filter. 20 bucks apiece plus shipping.

 

were they dbw or dbc?

 

i'm pretty sure he means air intake not intake manifold.
