🔍 WIX Filters 46891 Heavy Duty Air Filter - Ultimate Performance for a Single Pack Review

I replaced the original air filter on my 2017 Monaco bus. This filter replaced the original filter 546891. It fitted perfectly.

The filter failed after a month. The paper is separated from the outer tray on the inlet side. Not wet, but obviously broken.

Works like a champ! I replaced the original air filter on our Fleetwood RV with this unit. The original wasn't WIX, but this filter was identical and worked great.

The filter I received had a production date of about 5 months which I appreciate. It is always dubious to buy these high performance filters online as you really shouldn't fit filters with old production dates as there is a chance they will fall apart and ruin your expensive engine.

The item is packed in an old torn cardboard box with no protection. This will damage the inlet flange. Also, the product was manufactured a year ago, which may affect its useful life. Return to Revain and wait for a replacement. Update: Replacement properly packaged and in excellent condition. Manufactured on 12/21/20 which is more than acceptable. Rating changed from 1 star to 4 stars, would have given 5 stars but due to the hassle of returning the first item.
