i have bosch plats rite now and I got duralast wires cuz thats the only wires they had at autozone and I needed them. I just put em in last week and my G runs alot better now(mainly because my plugs were old and my wires were fu**ed). I had NGK's before that. I dont know. I dont think there is a big difference in plugs and wires. Just a bunch of hype like most products....
