This is incorrect. Look in my dyno thread for all of the pertinent info. I have nearly 30 dyno pulls (total, not all listed) on my car and carefully outlined each change and the respective pulls associated with them.

I think he has a totally differant engine based on his profile, I'm guessing it isn't apples to apples for him..

That is a good point, I didn't think to look at the profile.

He could have made back-to-back runs, putting in the K&N last w/o an established baseline on a heat soaked 1.6 ecoboost.

Without the data, it's just words.

Does the drop in mileage come from the active grill shutters no longer being able to close off the front lowering the areodynamics of the car?

I've thought about that. I have the bottom portion of both triangle grills opened up as well. But, I did pull a hand calculated 38mpg tank last month while on a road trip. My Fuelly still has me above 32mpg for 13K+ miles, so it's still the best mpg vehicle I've ever owned.

I might close off the triangles again. The newmission tube will still have access to non-engine compartment air, it just won't be impact air. I'll run a test like that over the winter, but winter gas might skew my results.

Today I installed the K&N drop in and I did not yet removed anything else. I may say that the car is acting a bit better and is a little bit quieter now than before (saw this at WOT). For those who might ask, yes, I kept the lid on.

There is still the little "shake" while the car is "idle-ing" but not as much as it was before. As far as I read here, it seems that if I do the snorkel delete, the "shaking" would be 99.999% gone and I'll have some sound increase. I'll test it for two tanks without the snorkel delete, I will then do the snorkel delete and post my thoughts about.

Ok, after 2 tanks I can say there is definetly no loss on mpg using the drop-in. In fact, I'd say it is very possible to see some gains in mpg's. The throtle response is better and the car is breathing better. And yes, it is more silent with the drop-in than when with the stock filter.

I did this hoping to get rid of the excessive vibration in my car. I also have a drop in. after 300 miles it still feels like i'm pushing a finely tuned lawn mower. Flip side there's no reason not to do this, if you like putting your foot down and don't have money for a sri or cai.

In what is for the vibration, you should go to your dealer shop and ask for a PCM/TCM reprograming. It should help. For what is a SRI or CAI, I had one (K&N), found it too loud for my liking and I sold it. I like the drop in and the car is smoother and breath better, IMO.
