Are there any one piece intake manifolds available for this engine.
I2 piece intake manifold leak caused engine failure on 1998 Buick LeSabre

If this is a 3.8L V6 then it should have a black plastic upper intake, and they do not sell an aluminum one for this motor. There was an aluminum intake in the early 90's and very recently they went back to that design, but to answer your question, no, they do not make a one piece design
you can not put early 90s intake on 98 model
