ISL Air Filter

Needing to change my air filter on my ISL 400 Cummins. Currently has an Ecolite filter (#546891) on it but found out that number is discontinued.

Any recommendations from others on what might be the correct filter to order and from who?

This is like the Tire issue...I replaced mine with the K&N, they make 2, an inside or outside intake, I have always ran K&N in my vehicles with no issue.

According to Wix, that is an old number for one of their filters. The new number is 46891.

That number also crosses to a Baldwin PA2721. Baldwin makes very good filters.

Jim

Since our coaches are only a year apart, this may apply to you.

When I got my coach (I'm the original owner) my air filter was the wrong size. Monaco, under warranty, replaced the air filter plumbing with a larger intake. If you measure your existing filter, if they are same as mine, any of these will work. (diameter 11” x 24”long x 7” inlet)
Air filter Donaldson P537448 or Baldwin PA2722, fleetguardAH8503 or Luberfiner LAF1848

hope that helps.
