I was told by HD dealer that part #29773-028 is a new improved Scereaming Eagle Breather Kit that uses the original breather bolts and funnels any residual oil directly toward induction throat. It appears to be the same concept as the Ness Sucker and completely compatible with the previous mapping. It did have the new white and blue filter that specifically states "do not oil". Dealer says that this new system will not allow the oil to drain back to the filter and that ,yes, oil will deteriorate the filter material.
They say that the previous system ,which I have,which used different breather bolts etc will always drain down through filter.
I know some of you have used the new air filter but anyone installed the new kit?
The production date on the box was stamped 7/05 so I assumned this was the latest version?
By the way,before completely examining new product dealer tells me that new filter just looks different,wash it and then spray with oil!!! [smiley=confused5.gif]
