Intake Manifold

[Boltazar]

Hi All, I have a crack in my intake manifold. I have a 2000 GMC duh sierra 1500 5.3 If you would, Pros and Cons on going back with a stock manifold or somthing other. Not into speed over 80 mph but would like to get better mileage. ( Don't say slow down ) If a after market manifold would help I'll spring for the bucks, if not I may glue the bloody thing back together. Your coments would be greatly appreciated. Thanks

i bet an aftermarket one would cost about the same or a tiny bit more than a stock one from somewhere. and you would get a nice performance gain out of an aftermarket one

Agreed, they would help with milage and hp also.
I will be getting Flowtech.
