    Make long story short. I bought old ones from pt.net and they were 42 so i was told but when truck got tuned by tunner he didn't like how my v.e table looked and he changed them to 8.1. When i took them out over the weekend they looked the same to me. So i don't know. I will have the old one clean flow tested to see what they are.
