Reviews of Autolite parts For Business

Good old standard Autolite Coppers work just as well as anything on the market, as long as you replace them every few thousand miles. At $.99 a piece, you can't beat 'em.

the plugs are autolite platinums AP3924. the wires are the blue ignitors from techtonics. the rest of the ignition is stock. do i regap the plugs, or should i leave them where they are now. i'm leaning towards leave them since it ran fine before and i don't want to deal with a no start issue when i start it or the first time with the new cam.

I use Autolite plugs plat 1 cheepos that get me 400 miles per tank and seem to handle continuous high rpm output ( drove across the US in four days)

Autolites last as long for me as the NGK's. Either of them last about 10k miles for me. Any longer than that and I start getting missfires. The Autolites can be found for about $1.00 each

Once we got a good local supplier for Motorcraft plugs a few years ago we almost never install Autolite.

There seems to have been quality issues with those for quite a while. I couldn't count how many times we removed fairly new Autolite spark plugs and replaced them with a better brand to fix a misfire.

I wouldn’t put autolite plugs even in my lawnmower. NGK or Denso only.

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

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.

I’d never put autolites in a Jeep, send em back and get champions or NGK depending on year and model.
