K&N filters for Stihl models

[jmester]

Will those OUTERWARE fit the stock hd2 filter. I would assume they do. Would just like to clarify.

I have had problems with the outer-wears filters trapping saw dust in the filter. Keep an eye on it, sometimes doesn't seem to work way it is supposed to???

I never liked any type of wrap on a filter.
Seems to pack full faster

I use to stretch the prefilters from the original hd filters over the hd2 filters it worked well but was to restrictive for air flow. The outerware are cheap enough maybe I will give one a try. May a least help to keep the filter a little cleaner from the big chips that get stuck in there.

I didn't like the foam outer filter that K&N market as going with this filter
It didn't stop diddly squat.

So I ordered a few of these. They will work much better.

Those seal good with the 084 stock cover?

I think the k&n seal well. Nothing got by the k&n filter that is on my 084. I have the same setup that brewz has. Just bought an outerware for it to get rid on the foam k&n prefilter

The 25-4250 number is for the foam prefilter. The E-4250 is the filter. That is being talked about.

Yeah sealed perfectly
If you to go back a page or so I posted a pic of the filter after cutting up an entire dead dusty tree.
Nothing got past.

The red foam pre filter is useless though

I probably seen it and didn't pay attention since I didn't have an 84 at the time.

I went back and looked at it. That was a month ago[emoji1]

A quick update after 3 hrs of run time. IMO it is doing a very good job at filtering... barely any fines are making it through. The outerwear cover is also collecting those little fines better. Also I peaked under the cover and the filter is about spotless. Maybe it directs air flow better?

Did you happen to notice any improvement in the saw operation? Just curious.

 

[CR500]

Not really, I had to richen the carb a bit. Throttle response is still very crisp

OK. Thank you. [emoji106]
