Title: I woudn't buy these again
Review: Buy something more standard. The 4 electrode thing doesn't help at all for fuel economy or power. It may even make them worse. You can't gap these plugs and the wire that the spark comes out of is very small. One of the 4 plugs didn't work correctly. My car ran then when I tried to start it a second time, it wouldn't run anymore. I ended up having to find which plug was bad and replace it with one of the old ones. I'm nervous that the other 3 are going to randomly stop working. You are better off buying 99cent plugs at walmart.
