Spark plug Bosch or Autolite

I went with Bosch but you really can't go wrong with the 4 vendors you have listed.

I put autolite's in my 2010 V6 and they've been perfectly fine.

Bosch Spark plugs Motul 0W-20 VW oil for the last two oil changes, about 3k miles on the current change AFE air filter Brake fluid flush within last year or so Coolant flush with VW fluid within last year or so Accessory drive belt New belly pan screws and fasteners

I ended up finding a post where somebody was having a similar problem that I was and one of the top comments on that post a guy had said word for word "I hope you don't have Bosch Platinum plugs in there." I ordered NGK ZFR5N copper plugs. I just received them this morning and got work. Gapped them to 0.035. Put them in. Done. Misfire gone. Runs perfect idles like butter.

I find that chevies and dodges like autolite or delcos, fords i run motorcraft only, japanese stuff gets ngk's or bosch.

I ran them for awhile in my Passat VR6.They did decent.Burned really well actually. I think when I was running them I only got about 23 MPG.

Do not get Autolite, I've seen them cause trouble and issues in Honda engines.

Although I prefer Bosch sensors over other brands in certain parts of my Mk 5 2.5, I will not buy Bosch spark plugs. Many professional mechanics over the last 3 decades have told me horror stories about them.

Yesterday, I installed new spark plugs in my 2004 TJ. Going off [this thread](https://wranglertjforum.com/threads/what-are-the-best-spark-plugs-for-my-jeep-wrangler-tj-4-0.4196/) I purchased the Autolite XP985. Originally, I gapped the plugs to .04 based on [this thread](https://wranglertjforum.com/threads/spark-plug-gap-for-4-0.17415/). The jeep ran terribly and actually threw a check engine light.

I went back today and changed all the gaps to .035 based on the note under the hood, but I still think the idle is a bit rougher then what it was before the change.

Warning about Bosch spark plugs!!! The piece of ceramic around the electrode failed. These were in a 2018 sonata turbo for about 10k miles. Thank God it didn't fall in...
