All 2.4ts are the same
All will give some gains but they are negligible.
I prefer the set up of the EST but they are all pretty decent.
If you look at the physics of it, EST is probably the most free flowing and WON'T take in hot air when you are moving, no matter what you are told.
If you go with the EST i recommend removing the weather stripping at the rear of the hood.
Also EST is a forum sponsor and a pleasure to deal with.
