1. Price is pretty cheap.
2. I have never seen white Autolite plug boxes. Always orange.

With returns, i'm almost not willing trust rock auto for spark plugs. I buy from a local store.

I won't buy spark plugs from amazon or ebay.
 
My experience last time I bought set of NGK laser irridum for 2018 Mazda 3 from Rock Auto nice price after discount of 5% but I installed it it no power odd noise,removed it went autozone get ngk rutherium installed it ,good power and sound good. Even daughter in law noticed the difference.
 
I got scammed from an ebay seller (who had a ton of positive reviews) who sold me counterfeit Denso plugs for my Rav4 back in 2020. Started getting misfire codes after about 19,000 miles. At that time I had no clue spark plugs were being counterfeited. Lesson learned...
 
Just get your plugs from the local parts store. Read/watch how to identify fakes and inspect them before buying. You're unlikely to get a fake set from AAP, AZ, or O'R, but I still check them anyway. Even top shelf genuine plugs are dirt cheap for the use you get out of them.
