Hi all,
A few weeks ago, I made a 400+ mile road trip and figured it'd be a great chance to compare the CTS intake to the stock air box. I simply installed the stock intake on the way out, then installed for the CTS intake for the return trip, recording mileage via the onboard calculator. I expected to see slightly better mileage out of the "less restrictive" CTS intake, but to my surprise the calculated efficiency was identical. Both got 40.4 MPG, with little regard for driving efficiently on my part. My average speed was mid/high 60s and the temperature was about the same for both trips. Note that the rest of the car is totally stock, too.
I guess there's no reason to get an intake without a tune, unless you're just in it for show/sound. Maybe I can convince my wife that we need a stage 2, family race car... But hey, good news is that 40 MPG is pretty good for a gas car!
