Is this the ventilator we're discussing ?https://www.harley-davidson.com/stor...18-29400299--1

 

No sir...while that is the correct “ventilator” for the M8, we are comparing the Stage 1 versus the Arlen Ness (both retain the stock M8 air cleaner cover).

Anyone notice how much of the Ness element is covered in rubber

 

Doesn’t really look to be much different than Harley’s

 

I noticed that also, if you blow the picture up you can see it clear. After the top and bottom rubber the HD may have more open element, kinda weird Ness would do that.

 

Cooky, was this the "Ventilator" that you were wondering about when you were asking if that was the one being compared? Cause I was wondering the same thing........ I believe the you/I are correct that the one you posted a link of is indeed the one in this Dyno Chart.

 

I had Rinehart Slimline Duals installed at Hulten Speed Sports Our local Dyno Speed shop An he installed Arlen Ness Big sucker,It dynos well an You get to keep stock cover minus The plastic,An the Price is good.

 

Thanks man it had me a little WTF for a bit there.
Cheers.
