Good value
I have used Autolite spark plugs many times. They are good quality, and my engine performs well with them. They are easy to install and helped to increase the power and efficiency of my engine. They were the correct size for my car, but I would recommend checking the gap before installing them.

Clean and perfect fit
Just as clean as you would get from a popular chain autoshop. My Buick Encore's engine runs smoother after 30,000 miles swap from the last sparkles I've used.

Very well made
Compared to the old spark plugs that came out of my car, these ones are by far better quality! They were easy to install, I just needed to change the gapping a bit for my car.
