I'm just looking for more options and I'm still waiting for concrete evidence from Wagner that their product does what it claims it does. When that happens, I'm all for considering their IC for my car. I'm also not in a rush to buy any IC at the moment. I'm focusing on the Quaife TBD and suspension swap for this spring.
Last thing I'm doing to my car is the IC and engine tune. For myself, they are pointless until the other aspects come first.
