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.
Pros: runs exactly the same
NKGs are the exact same plug just different label and cheaper, and are much better than the stock plugs.
Pros: better than stock plugs
Cons: different label, cheaper
Those look great last time I did mine they were all carboned up but I was at 300k but definitely made a difference in Fuel economy and a little less sluggish
Pros: better fuel economy
Cons: a little sluggish
Mileage: 482803 km
I’ve owned my truck for a year now and just decided to take out the spark plugs to see how old they were… mfs were the original factory plugs 14 years old and ran for 246k miles.. basically got a brand new truck now haha
Pros: brand new truck
Mileage: 395906 km
Yeah can go wrong with acdelco. I run Bosch in my 93 4.3

I'm getting some knocks in all cylinders in the first revision, more than I did with the Cobb OTS map and stock spark plugs. Hopefully it gets sorted out in the next couple of revisions and if not, I'll have to check the spark plug gaps or maybe re-run with the Cobb OTS and see if the knocks are due to the tune or spark plugs.
Overall, the power delivery is great.
Pros: great power delivery
Cons: getting some knocks
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
