Bought a new 2011 EC 300 SD late fall last year. Have maybe 15 hrs on the bike - the stock twin-air filter does not seem to really fit the cage all that well and I was concerned about the sealing interface. No matter how careful I installed it the sealing surface at the cage flange always involved some of the foam filtering material squished into the sealing surface.
I took a chance and bought a couple of DT-1 Foam Air Filters and I like the way they fit the cage much better. Anyone else with comments?
The DT-1-190-47NO filter does NOT go over the stock locating cage pins like the Twin-Air. It rides on the flange surface and has a nenoprene type of sealing surface adhered to the foam filter material. Although the filter is not pinned to the cage at the sealing edges it fits the mating flange much better in my opinion.
Just thought I would share this with everyone. Quality of DT filter looks to be good to me - I don't have any cleaning (stand-up to cleanings) information to share.
