tried a search came up with nothing,what size engine does a 99 olds alero have?i know the achieva had a 2.4 in which you can use that intake mani on the cav 2.4,question is my sister has the alero,which threw a rod, so she's scrapping it,if it's a 2.4 are the intake manifolds compatible to my 98 cav 2.4?thanks

My friends 99 alero has the EXACT same intake manifold as my 99 Z has.
Both are 2.4l LD9s.

if its a 96-02 and a 4cyl then its a 2.4 twin cam
some 02's had the eco , but like the cavs its a transition
