Does anyone know what type on engine mods void the warranty on the m2. I have just recently purchased my m2 and want to do some mods but afraid to do anything and void my warranty...pls help
Depends on the modification/how friendly the dealer is/how much $ you have to attempt to sue if they say no.
Read up on the Magnuson-Moss warranty act, in a nutshell IIRC the dealer has to PROVE that your mods have caused a warranty claim, but that doesn't mean they won't try and pull some crap if they think you won't lawyer up.
IMO cat back exhaust and you'll be fine(header will void it for sure), if you do an air filter I could see any problems with the MAF sensor or end up with scratched cylinder walls they'll say it's from crap getting past the filter. Honestly I'll probably never even install a CAI myself because ones that work are great at sucking up water, and short ram intakes just suck hot air... might be okay for road course racing where you're moving all the time, but for autocross(which I do) it sits for a while and will get heat soaked, the factory intake is actually really good at pulling cooler air.
Doing a tune, if something goes boom obviously you're probably screwed... not to mention any problems that arise could well be because of changed parameters, I had my Mazda3 tuned and would get a very intermittent P0101 for the MAF performance about once every 800 miles. No driveability problems or anything and I didn't bother with resubmitting for a tune revision because it wasn't truly a problem(I'm a tech so I know a bit more about both sides of what goes on in the ECM).
FWIW I found out on my MZ3 that the O2 sensors are NOT covered under powertrain warranty, claiming it was a maintenance item/electrical and only covered under basic warranty.
