I recently read somewhere that all the avenger intakes are interchangeable.Well 95-99 avengers and 95-99 eclipse intakes will fit on a 2.5.So my question is.....is this true lol.

 

i hope you are referring to the air cleaner tube, from the throttle body to the air cleaner, in which case, mine look identical on the 2.0 & 2.5, so i would say yes. if you are referring to the intake manifold or plenum... no.

 

You may have seen it in the sticky area.
