Disappointed, stopped working fast
These spark plugs were a letdown for me. The Autolite Iridium XP3924 started misfiring after just a couple of months. I expected better durability for the price. Not sure if I got a defective batch or what, but I’m not happy with this purchase.

Installation was tricky
I had a bit of a hard time installing these Autolite spark plugs. The threading didn't seem to mesh perfectly, which made me a little nervous. But once they were in, the engine has been running smoothly. Just be prepared for a little fuss!
