Default K&N Aircharger...12.92 HP gain???

Anyone running one of these?
Seen the claim on K&N's site?
What's you guys thoughts on this intake?

Check this out...

A sister product to our 57 Series FIPK, our 63 Series AirChargerŽ Intake Kits are guaranteed to increase horsepower and come with a Million Mile Limited Warranty. K&N intake systems replace your vehicle's restrictive factory air filter and air intake housing. K&N intakes are designed to dramatically reduce intake restriction as they smooth and straighten air flow. This allows your vehicle's engine to inhale a larger amount of air than the OEM air filter assembly. More air means more usable power and acceleration throughout the engine's RPM range. The filters on these kits are washable and reusable. Most of our intake kits are relatively easy to install using tools commonly available (see installation instructions). 63 Series Intake Kits are not legal for street use in California and some other U.S. states.

63-1122 Product Specifications
Product Style: 63 Series Aircharger Kits
Estimated Horsepower Gain: 12.92 HP @ 4612 RPM

The only way you would get 20% hp increase with that ac is with a tune!

We have tested the K&N Aircharger on our 09 bike and on the dyno the numbers we identical to the standard stage 1 air cleaner. I currently have this air cleaner on our bike at the moment. The gains you get from a forward facing filter design are at speed in real world conditions. This does have a very good fit and finish as is less money than the SE Heavy breather.

If anyone has pictures of this installed on their bike can you post them. The SE heavy breather looks good but doesn't do much for performance.

I want to see how this looks installed on the bike (I have an 08 Street Glide) before I invest my $$

is there a version that fits an 07, and how much do you sell it for?

Does a remap need to be done if installing one of these AC units? I love the look of them, and was satisfied with K&N products in my sportscars.
