Only one, not four
The description says pack of four, but I only received one spark plug. This is highly inconvenient as I now have to go into town to buy a set of four in order to replace them tomorrow as planned. So much for the convenience of ordering online. I see now that another reviewer had the same experience.

Big improvement over oem
After shopping local for spark plugs, I found these. Got 4 for the price of 1. First thing I noticed after installing was quicker acceleration, better fuel economy and overall better performance. Will order again when the need arises.
