I bought 3 new LC4 plugs for my cars and my RS4 killed them all. I put the first one in, and after it didn't start for a while I checked the plug and it was dead. I grabbed a new one, checked it before putting it in. After the car failed to start, I checked the plug and it was dead also. 3rd one did the same, car never started.

Again this is on a RS4 with Nitro Star T3.0 engine.
