Review on 🔌 Autolite XP6203-4PK Iridium XP Spark Plug Set (Pack of 4) by Justin Garrett

People seem to say Autolite isn't that good but I can't understand why some people think they are of lower quality. They don't make sparks either, are they made of cheaper material? Aside from a few negative reviews stating the spark plugs failed (which all products do), it's hard to see why they're worse. This is the second set I've bought (the first was for another car) and they worked great with the first set which has been fine on my other car for over a year. Anyway, I'll be changing the spark plugs in about 40,000, especially at this lower price point, so I'm not worried. Maybe they wear out after 100,000 miles instead of 150,000 like the "best" brands, but I won't use them that long.
