I know there is much discussion here about the "fines" getting into the combustion chamber on the 500I's and many posts about aftermarket air filters that reduce this intrusion.
My question is this:
I had recently surfed the Stihl USA website (not the one which directs to you a local dealer) and compared the "features" of the "500I" to the "500I W." The 500 I W mentions "The new HD2 air filter , made from PET material , featuring a radial seal which prevents the intake of fine particles", whereas in the 500I section of features there is no mention of this new filter. The illustration in the 500I W features appears to show the filter pleating with a darker / charcoal color of the filter. My 500I has the standard white color pleating.
Am I overthinking this, or are they one in the same or?
My limited parts manual lists the filter as 1144 140 4402. I tried, but found nothing on the 'net regarding differences or pictures. Is this just Stihl's marketing? Maybe Stihl's admission of a problem with fines?
Thanks to all for any insight and help.
