i cant find anything for the evo 9. are all parts from the 8 interchangable??? it is a dumb question but if you think about it, the 9 has enough changes, so i dont know if the: intakes, exhausts, bov's, intercooler piping, interior meterials etc etc...

I'm confident that most parts for the 8 are compatible with the 9.....there may be a few exceptions like exhaust and cams, but everything is pretty much the same. I believe the only major changes to the 9 are the addition of MIVEC and the turbo is different. Others will probaly give you a more accurate answer though.
