Unfortunately we aren’t big fans of aftermarket throttle bodies for the drive by wire 2005+ cars.  We don’t sell any throttle bodies that fit the 2005+ cars because in our opinion they are not a true bolt on.  Some customers have used aftermarket throttle bodies and have had decent luck but I’ve had too many customers that ran into drive ability issues which is why I refuse to sell them.  I’m sure there are some gains to be had but the potential for issues in my opinion make it not worth the effort.  I’d rather see you put the $$$ into suspension or other modifications that will give a more noticeable gain.
