After researching this forum it appears many people believe that placing a new CAI or simply doing a drop in K&N filter on the stock CAI have the same benefits and the most benefit can be derived by adding a custom tune to go along with either of these.

With a simple drop in K&N filter and no tune I know you will not be able to tell any difference in power but has anyone done a real world test to see if it does increase mpg's and if so by what amount?

Thanks again!

I don't have a direct answer for you.

However, when I was rebuilding my '05, I had the front bumper cover off the car to drive it from one shop to another. The change in air flow patterns through the intake (it's a Kenne Bell CAI located inside the bumper cover) caused the car to run poorly at anything but WOT, even with the exact same K&N filter installed.

When I tried to run the car without the K&N installed, it would barely idle.

These cars can be very sensitive to intake mods.

No question that a tune will be required to get maximum gains.
