Spark plug Autolite or AC DELCO

I replaced them with AC Delco 14 Platinums, and it seems to be running better.

I have autolite xp in the van. $100 for 6 ngk, $90 for denso with a van with 250k miles. Everyone says there crap, but it runs great.

Just did mine with ac Delco, gapped them in advance and running great!

In my personal experience (99 suburban 6.2l 383) AC Delco spark plugs are the way to go

I bought some Autolite double platinum spark plugs because they were on sale at the Napa where I live but everybody I have tried asking to help me do my spark plugs has gawked as soon as I say "Autolite" and tells me that I'll have nothing but issues with those plugs and that "they're only good for Fords" basically.

Don't use AutoLite plugs in this car, they are known to have issues.

Also, Autolite is extra terrible. I would have done anything else.

Local mechanic used an Autolite plug, not Honda-recommended NGK. Misfires stopped for a month, then happened twice more. I have since discovered this brand does not run well in a Honda engine.

I changed my plugs to autolite because I had never heard anything bad about them. I replaced them after 3 weeks due to misfires, put another set of autolites in and it ran fine for 2 weeks. Started misfiring again and swapped in a set of NGK's, no problems since.

I would never install Autolite on any car, definitely not the WRX.
