This week I had the dealer replace all 4 coils under warranty. They actually tested fine, but the service manager is really cool and was aware that mazda's simple "resistance" test procedure isn't really adequate so they just put new coils in anyways. There was clearly something wrong with the old coils as the replacement merited a night and day difference in performance. I guess using a scope is the only really good way to test as it seems most other methods yeild unreliable results.

checked with local dealer here in Finland, and they were not aware of coil problems nor understood when I asked them to test my coils and told about multimeter testing... and also from the local 8 community none had heard anyone here having problems with coils... the list price for a new coil is ridiculous 157€ so I would assume that if coils were causing problems guys here would know about it.

I'm pretty sure my coils are gone, because I can't even drive about 6000 RPM's without bogging my engine with unburned gas...
I think my warranty ended but I wonder if my engine warranty still exists... I have no idea what the cheapest warranty is for our 8's @ 53000 miles

well my dealership said that my issue is either because of the coils or because of engine internals... He also claimed that coils wasn't covered under my drivetrain warranty, is that true?

Tell me how does the ignition coil NOT powertrain related ?
Tell them to do it, or going to talk with MNAO
(Unless you're out of warranty)

ya, well right as I left for work my dealership also asked if they could add a possible 260 something too the bill for me too pay because I have too much after market stuff... They said that they would pay the 260 if the issue is warranty related... I told him too just check the CEL and he should be able to figure it out from there... Something tells me that this dealership might be attempting to gain a couple bucks outta my pocket... because he said he had too "look up" and see if the coils were under warranty (which I still don't know if they are)..

Coils are Covered under your basic Warranty unless something caused it to fail outside of normal failure becasue of a faulty part. If you put unofficial wires or something, they can deny it.
As far as under powertrain warranty, dont think so. Power Train Warranty covers anything Internally Lubed of Engine or Transmission.
I think Ive ran into my first bad coil, need to replace first to see if problem still exist though.

This whole situation is totally bunk, I can't believe Mazda wouldn't cover something I have no control over. Even if you got new wires, that doesn't support the fact that Mazda's coils only lasted me 50,000 miles... Complete junk... And when they fail the engine only destroys itself? Cool I'll pay for a faulty design of Mazda's....

Well Im not saying that they should not cover it but if you have anything aftermarket or non-original OEM parts they can use that as a excuse.
Ive heard of dealers doing that but I would either take it back and say I know that part is covered, give me a reason why your not fixing it or just call Mazda.
A coil is covered for your basic warranty, not power train. If they want you to buy a coil ask them why and why its not covered.
Im about to warranty one on a vehicle that has 48K.

tell them explain how can an intake *melt* your CAT. in a scientific term, not *because the tech said so*, dont buy this kind of bullshit.
new set of coil cost about 120(w/ shipping) , I got mine from OnlineMazdaParts.com, or you can get them from finishlineperformance.com. both forum vendor both extremely helpful.
These new coils gave me better respond and less idle virbration. Updated part from Madza.
You can have aftermarket stuff on your car, but you have to make sure that in case they're being a dick about it, you have to know how to counter their bullshit.

Power!!
Sounds like you need to find a new dealer friend. There should be no way your intake is affecting your cat. Unless you mean your Kitty cat is physically being eaten by your intake. In that case my advice is don't take the brown acid.
My advice:
1)put your stock intake back on.
2)take the car to a different dealer
3) get coils replaced under basic warranty and cat replaced under powertrain warranty.
4)Put intake back on when you get home
5)keep your kitty cat away from intake.
6) Zoom Zoom!

I got charged 179 bucks so the tech could figure out that my aftermarket cat is dead.
The service advisor, "advised" me that since I changed my intake my car is running differently, and eating my cat. My rx8store cat has been eaten anyway, and isn't related too my intake at all...
I just wasted 179 bucks for some mechanic too tell me something that I should've figured out myself...
Now that most of my stuff is aftermarket I think I've learned the lesson that dealerships are just going too use what I have as excuses to take my money.
