If you are refering to K&N part number 63-3056 we have sold a few. Around a 10HP gain...

Based on "TurboTechRacing's" earlier post, back in Sept. I took my truck out to K&N and had them install the Fuel Injection Performance Kit for HHRs then run it on one of the chassis dynos on K&N's R&D department.
The performance increase wasn't quite 10-hp but it was credible. Executive summary: on average an increase of 8-hp and 6-lbs/ft torque, SAE-corrected at the front wheels. In addition to the convincing performance improvement the K&N had none of the fit problems I experienced when I tested the Airaid intake kit last year on my HHR five-speed. For more info on that see the following threads:

The K&N also is better looking that the Airaid. Lastly, unlike the Airaid which is open in the front, the K&N FIPK fully encloses the filter which I feel is a better design.
In a few days I'll post a more detailed account of my experiences with the K&N FIPK.

I doubt anyone's going to feel anything from any cold air intake without a real ECM tune for the new airflow. From what I've discovered in the Mustang community, nobody running a real performance car just bolts on a CAI. Everyone expects to pay for a tune that'll maximize the performance of the CAI and wring every last bit of power out of the new airflow.
That is, of course, if you believe that the stock airbox loses more airflow than the plastic tube you're bolting on in its place. Or that the intake tube diameter on the aftermarket CAI is any bigger or flows more air than the stocker.

Well, the filter on an aftermarket intake obviously poses less restriction than the stock one does. As far as "feeling" any gains from just bolting the unit on... it's not gonna happen. These intakes gain 10hp at most, you can't really feel that.
On the tuning subject. A good retune is going to make the most out of any modifications to your engine. That being said, if you are planning on adding multiple bolt-ons over time (intake, header, exhaust, etc.) it is simpler to wait till you are done and get retuned once.
