Spark plug Autolite or AC DELCO

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

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

Note that decent spark plugs are hella expensive, but worth it due to lasting a lot longer than cheap $4 Autolite's.

For what it's worth, here's my 2 cents on plugs and wires. I've read several threads here that indicated something along the lines of, \"YOU'D BETTER D@MN WELL USE NOTHING, I MEAN NOTHING BUT OEM BRAND PLUGS AND WIRES!!! THE CAR IS TUNED AT THE FACTORY USING THESE. IF YOU USE ANYTHING ELSE, YOUR CAR WILL RUN LIKE SH@T AND YOUR FUEL ECONOMY WILL BE TERRIBLE. YOU'VE BEEN WARNED!!!\" Fast forward to a few months ago when I had a breakdown an hour from home and was trying to figure out the problem. Because I was on the side of the road, I had to Uber it to the nearest parts store and take what they had on offer. If I remember right, the plugs were Autolite and the lightning hoses were Carquest (don't quote me here). No Bosch, no Bremi, etc. I was nervous about it, but hey, the car's 20 years old, so I wasn't worried about squeezing out the MAX performance. Guess what? It runs exactly the same as before and gets the same gas mileage.

I bought six ac delco spark plugs from Rockauto and half were made in France and half were made in the US. There are very slight differences like the diameter of the electrode and how deep the plug is on the end that goes into the cylinder. Even one of the US plugs is different from the other two.

Put autolites in my Durango, ran like junk nd put NGK in and better.

With almost every car, using OEM plugs is the way to go. The one brand to ALWAYS avoid is Autolite. They are extremely poor quality and I have never seen them work long enough to justify the cost saving.

Autolite plugs are bad.

Do yourself a favor and throw Autolite plugs in the garbage.

Bought a set of iridium plugs that were wasted after 15k miles. Amazon gave zero fucks. AC Delco gave zero fucks. The scum bags who sold them changed their name and keep selling.
