???3 Denso, 3 NGK????

[cmar]

So i went to the dealership and bought 6 denso iridium spark plugs. When I got home and changed them today, to my surprise there where 3 Denso, and 3 NGK plugs. Anyone heard of this? I called the dealeship and told them and asked why it would be like this, they said that the plugs were very similar and that it dosen't change the performance. Does anyone know why they do this and/or do you have the same setup? just wondering

It's not only common it's the norm. Try a search and I'm sure you'll find more.

My '05 was the same just put 6 new denso plugs in and you will be fine.
