the k&n is just a better filter, prol won't flow different enough to worry about having to have it there for the tune. I cleaned my stock filter about 3000 miles ago and just did it again, pretty dirty in the throttle body. i'll be very happy when i get my k&n.......

 

Well guys I just got back from the dealer, and had a new rear tire, rear brake pads put on and maintenance service on the motor. Along the the K&N filter installed.
I really didn't get on it too much. From my butt dyno, I felt a difference. The main difference is a paper filter vs a real filter designed to catch all the tiny particles. I can truly say that you can really hear the throttle body open up more and suck up more air. I could not hear that with the paper filter.
In short, K&N makes a great product. I am pleased w/ it, and just knowing that I don't have that paper filter on my scoot is good enough for me.

Well... My dealer actually kind of talked me out of the K&N today. The stock filter isn't paper, it's a polyester type fiber media, similar to oil filter type media. If it was paper it certainly wouldn't be washable. The K&N might breath better but is it actually filtering better? I see a couple of you had dirty throttle bodies with the stock element. K&N's are known to let smaller particles through until it has been used/filtered a little bit. Maybe the extra suction of air intake might equal larger filter micron openings for particles? I guess I'm playing devils advocate here as my last four bike filters have been K&N elements and the Ventilater is my first polyester type filter (not to be compared with paper). The MoCo already does use K&N filter media in many of its SE air filters. They certainly could have initially used it in the Ventilater. Maybe they now offer it as a replacement alternative in lieu of a performance alternative? I'm still on the fence here.

 

Could someone include a picture of the new filter?

And does anyone have the Spring 2011 supplement in pdf?

Thanks!

My understanding from talking to both K&N and the regional HD folks is that the reason moco didn't have K&N for the Ventilator is that the two have been negotiating a strategic agreement where K&N will become an official OEM supported part for all hd engines. That agreement has just been signed. All things equal, an oiled filter is the best alternative if dirt capture is paramount. Military vehicles worldwide depend on them. I'm certainly not knocking the apparent quality of the Poly filter on my Ventilator because it has stood up well to rain and washing and still looks new, but I'd prefer to have it oiled. My new K&N arrives on Tuesday. Dirt cheap considering it'll last for years.

 

LP,

Here you go. Not the best photos, not much light in the old garage and it's from the
cell phone. But I think you can get the idea.

Mfuchs & Troop,

I do agree, I'm not trying to trash the stock paper (polyester type) air filter either. It has lasted almost two years. I'm just very happy with K&N air filters. Like I mentioned in my first post, I have K&N's installed on all my motors.
