Owner reviews for ignition coil

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

I got all 6 of my ignition coil for my 4Runner for the price of one at autozone. They were Denso oem for Toyota.

Don’t get Bosch coils or plugs. Get Delphi coils, they’re the updated design. As for plugs go with NGK

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 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

I’ve used both. Didn’t notice any difference. Have Delphi’s right now. Both work great for light and mid tuned setups.

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

They do fit but I'm not sure if they are any better than standard ones. Didn't drive enough to notice any difference.

Just replaced my coils. AVOID Bosch. Literal trash that does not even work.

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.
