K&N E-4425 Air Filter Product Reviews

Thursday, September 21, 2017 - Part E-4425
Bought this filter for my Steiner mower and like any other K&N filter I've ever purchased, I was not disappointed. Definitely less restrictive than the paper filter. Have my mower more power while using less fuel. I should've bought one sooner. Definitely recommend it.

A perfect replacement for the expensive and hard to find paper filters. This is the second one I bought. The first one is also the same model No.but for a different mower. After one year of weekly service, the filter is clean and non restrictive. Unlike the paper and foam cover unit, which would have been replaced 2 times during the season and the paper element was plugged, causing the mower to run rich. One of these is equal to 2 years worth of filters and I have cleaned the filter and oiled it and had it back running in a hour.

Perfect fit as a replacement for a 1997 (Brand Name) BG43. Will save me money and the hassle of buying (Brand Name) parts.
