K&N E-4425 Air Filter Product Reviews

Monday, June 6, 2016 - Part E-4425
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.

After years of throwing away OEM filters twice a year I now have a better filter that will last for many, many years and allow me to clean it providing better airflow to the engine. K&N quality is second to none with perfect fit. Money spent on K&N products is an excellent investment in increasing the performance, longevity and owner experience of whatever product it is installed in. Thank You K&N! Five stars simply because no more were offered!
