The last plugs I had in were ngk v-power and they only seemed to perform well for about 5000 mi. I know ngk is "THE BEST" performance wise, but is there anything else that has a longer life span? Has anyone experimented with some other brands that were descent that lasted longer?

 

On the 1.8t spark plugs are easy to change. On my 2001 A4 1.8t, I used NGK FPR6Q. They would last 40K mi.
