Seeing there 1000's made and they have the ability to make or break your engine which one is best for an NA6 Turbo.
I have 2 placed together about 50 mm apart infront of the cat. I dont know why!

Should I use the standard OEM or something different now there is a turbo installed?
Recomendations????
Blue Chilli (Ex-Lo Miata or Evil 5)
