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

I got all 6 of my ignition coil for my 4Runner for the price of one at autozone. They were Denso oem for Toyota.
Pros: OEM quality, good price
Vehicle:
Toyota 4runner
Don’t get Bosch coils or plugs. Get Delphi coils, they’re the updated design. As for plugs go with NGK
Pros: updated design
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.
Pros: cheap, extra in trunk
Vehicle:
Audi A3
Part number: 06E905115E
I did the LS coil kit, I ordered dragonfire plug wires and a harness adapter from ebay then just got the coils for any gm v8 really, I got mine from a 2013 Chevy 1500 with the 5.3, they have better coils that last longer and produce a better spark
Pros: last longer, better spark
Vehicle:
Mazda
I’ve used both. Didn’t notice any difference. Have Delphi’s right now. Both work great for light and mid tuned setups.
Pros: work great, no difference
Vehicle:
BMW
I did Oem plugs and Bosch coils. No problems so far.
Pros: no problems
They do fit but I'm not sure if they are any better than standard ones. Didn't drive enough to notice any difference.
Pros: they do fit
Cons: no noticeable difference
Vehicle:
Volkswagen
Just replaced my coils. AVOID Bosch. Literal trash that does not even work.
Cons: does not work, literal trash
In January 2021, with about 40k miles, the coils went bad. I replaced them with quality Duralast coils (made by Bosch) and new iridium spark plugs. Fast forward 6 months, and I had a misfire again in cylinder 2, so I am now on my 3rd set in less than a year. The Duralast coils have a lifetime warranty, so whenever they go bad, I can just swap them out at Autozone for no money, and it takes all of 10 minutes to swap them. But I dont want my car misfiring and breaking down at an inopportune time.
Pros: lifetime warranty, easy replacement
Cons: repeated misfires, frequent failure
Vehicle:
Hyundai Sonata
