Default Doherty AC....any feedback?
This AC is double the cost of FM and HD. Is it that much better, or is the price just due to the material(billet)?

The price has a lot to do with the Billet, and you also get the one-way breather units. It's the best quality air cleaner setup I've used, the thing really is a work of art.

I'm very happy with mine, but I didn't pay retail for it........I picked it up used from another forum member.

Yes...the Doherty sports an external breather, AKA, a ********...instead of feeding blow-by back through the injection system.
Inside those *********, is a one-way valve.

Also, those aren't included.
You order the PowerPac...or, the PowerPac with Powervents, which is the *********.

Mine has been great. It is almost a shame to cover it up.

I had a doherty powerpacc with powervents on my 07 1200C before I traded for my 09 ultra. That thing was definitely a work of art and I loved it. wish there was a way to trade it for the powerpacc that fits my ultra lol price was well worth what you get
