I don't have one, but check out the site below, several magazines have tried the Doherty PowerPacc. 6hp to 10.4hp and 2ftlb to 6 ftlb of torque! If you believe the mags.

WV....yes, I believe it is, though I am not 100% certain about this.  In order to get the regular round K&N to fit decently, the thick gasket is required between the cover and the filter.  Not because of the seal, as the filter fits the baseplate just fine (the SE chrome baseplate), but the cover is made in such a way that there is a gap where the top of the filter meets the CVO football shaped cover on the Ultras.  The thick gasket helps fill those voids.

Although I did not actually fit the filter of the 3910 kit inside the cover, it appeared that it would work.  I wish now that I had looked into it a little deeper. :(


When I was doing my own SE on the 07, I was trying to come up with a slick way to fix the cover issue and wasn't being very successful, then a bud of mine who was over checking out what I was doing asked me "Why don't you just put a thick washer under the bolt to take up the space?"

It works great.

That's what I get for trying to over-engineer things.

Chief...that's what they provide with the Doherty PowerPacc...a thick washer between the cover and the A/C.  It'll all work, even without the gasket or washer, but it makes it all a little cleaner install.

And, to edit my earlier post...there is a difference in the covers on the 06/07 models from any of the other football type covers.  The other covers have an "indented" place for the round part of the filter to rest in...the covers on the 06/07 do not have this indention, so it causes a "gap" on the front and rear of the cover, which in no way effects the air filter itself, as the top of the K&N, Doherty, Zippers, Ness, etc is sealed to the filter, so air can only get in one way...around the edges.  I think K&N makes these filters for the other companies and they just call them there own.  Some are a bit thicker to provide even more air flow than the regular 0800 model.

That's what I get for trying to over-engineer things.
