vs
Spark plug Autolite or BERU
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.
Pros: good performance, excellent value
Cons: short lifespan
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.
Pros: ran fine before
Cons: no start issue
Part number: AP3924
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)
Pros: good fuel economy, handles high RPM
Vehicle:
Volkswagen Jetta
Now I'm running autolites one range colder than stock at .028 and they run great...
Pros: run great
I bought some Autolite Platinums and now I find out they are crap Anyway, I needed something fast. Replaced them earlier this afternoon after work and so far so good. Acceleration is ALOT smoother.
Pros: acceleration is smoother
Cons: they are crap
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.
Cons: cause trouble, issues
Vehicle:
Honda
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.
Cons: rough idle, check engine light
Vehicle:
Jeep
Part number: XP985
I’d never put autolites in a Jeep, send em back and get champions or NGK depending on year and model.
Vehicle:
Jeep Wrangler
I quit using autolite plugs somewhere between 1995 and 2000, got tired of all the comebacks.
Cons: tired of comebacks
