Whenever I need a coil, I try to find a Bosch blue first. For whatever reason they’re scarce, but I’ve always had good luck with them.
I also got my OEM coils for free but i do now need to replace mine, and will be going Bosch.
i ended up going with BOSCH 0986221072 ignition coils, no issues with stage 1 tune so far. Put almost 20,00km since installation.
Try 07K905715G BOSCH
Bosch makes a lot of the oem coils, so I wouldn't shy away.
I ended up going with Bosch and haven’t had any issues.
Just stuck a load of Bosch in mine, worked a treat, xHP throttle blip downshifts were sometimes jerky and causing transmission faults but now they’re as smooth as butt’uh.
I assumed it was bad and while it was sad to get rid of the OE Bosch, Autozone had a C831 coil that I was able to pick up. I think the boot was slightly too small but I’m 90% sure it’s making contact but I am still not getting it to arc.
I believe Delphi is what people switched over to because the Bosch coils were failing.
9-3’s eat coils; it’s a forever problem on my 9-3 that it seems like every 30k miles I’m spending $200 on new coil packs. It’s essentially routine maintenance. I ordered Bosch OEM coil packs off RockAuto and just now realized they have a warranty. I submitted a warranty claim and they sent me out brand new units. Wish I would have known this because it would have saved me lots of money.
