I bought a almost new 2008 3.7 I5 engine. Only 7701 km. Is this engine compatible with my 2006 h3 3.5l setup? The newer engine came with all wiring and PCM.



Thanks

From what i have read spec wise the only difference is the head. Everything else is the same. Oh except for the alternator,2006 is the only year that has your alternator.
