Well, I'll sell them when they have been tested and Tested , until I know they are completely 100% safe for your car. I also Have been tweeking with them here and there to see were the absolute best performance is. I want to sell you an intake system, that will blow your socks off. I don't want to offer a system that will only give you a 4.75 HP gain(Whidh it is not) Some other companies might do that, but not me. What I think people are forgetting sometimes is, that the development of a performance part takes a while to refine, and to mold into shape. Now I'm also a one man band here. I can not and will not sell you anything less then my best, I'm sorry that it has taken so long, especially to Mr. Root. Dude you have been the most patient of everybody So just hang in there guys.
