Ignition coil Bosch or APR

Always go Bosch. 55 years of wrenching and have never had a Bosch part that wasn’t top quality.

I like the R8 coils because they're cheap. At $20 per Bosch coil, you can throw an extra in the trunk without breaking bank. I did mine when my factory bolt downs went bad.

I did Oem plugs and Bosch coils. No problems so far.

I use the Bosch, and Ive been happy with them so far.

Bosch.

Never had issues with the Red Bosch ones I got from Shopdap.com But plugs, I preferred the NGK Ruthenium HX over the Laser Platinum, and Iridium-IX

The R8 coils are cheaper then the standard Bosch coils so cheaper if nothing else.

Many aftermarket coils are completely out of spec and do not work well, some can even destroy the ECU. OE, Bosch, Temic are all good, I believe Beru is an OE manufacturer as well.

One of my Bosch coils went bad within 13 months. Probably would have happened with Delphi for all my luck. Nevertheless, I returned all six to FCPEuro for lifetime replacement warranty.

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.
