coil difficulty level 1. Allen wrench and a 10mm are all you need. they are under the spark plug/coil cover.

Sounds too easy...will check it out next time myself, THANKS !

I have replaced with new and used coils. The coils that I replaced with brand new and low mileage ones were fine but once I replaced coil with another high mileage one because that was all that I could get that day nd it blew out after about a week. But by that time my other coils had arrived and I haven't had any problems since. Once I get my bigger turbo and head toward 900whp we'll see how my coils do lol.

Thanks for the interesting info. May I assume there is some correlation between HP and coils (higher = bad for coils) ? I'm obviously running much lower at 500 vs your 591 and 900(!) but it would be interesting to know if others >450HP have same issues with them.
* BTW - is the coil replacement a 10/30/60 minute job ?
* How can you be 150% sure it's the coil that needs replaced and which one that needs to be replaced ?

Thanks!

you can replace all of the coils in 10 mins. Like someone said earlier you just take off the spark plug cover with an allen, then use a 10mm socket for the bolt holding each coil in then unplug them and pull them out. When some of my coils went bad my car sounded kinda like a wrx and to check which one it is you can just unplug the coils one at a time until it idles normal again then replace the bad one. The ones that would idle and drive normal but would only have a blowout under boost are a little bit harder to find. Since I lived about 5 minutes away from my tuning shop I would just take it there and normally they would connect to my aem ecu and put it on the dyno to find the bad coil.
