Spring's Around The Corner - Time for a K&N Filter in your Lawn Mower or Chainsaw

Jan 19, 2017

The construction of K&N filters provides additonal capacity versus paper filters

K&N small engine filters have a greater capacity to hold dirt while maintaining airflow

Most enthusiasts are well-aware that K&N produces replacement filters and high-performance intake kits for cars, trucks, SUVs, and motorcycles. But most miss the fact that K&N also manufacturers filters for walk-behind and riding mowers, and chainsaws, along with other power equipment.

So why are we talking about lawn mower and chainsaw filters when there’s 10 feet of snow on the ground in parts of the country? Because before you know it the days will get longer and warmer, and the grass will begin to sprout. And we want you to be ready. Also, what better time to work on your tools in the garage?

Unlike modern cars and trucks, lawn mowers and chainsaws don’t have any emissions controls. You may be surprised to learn that a lawn mower produces as much pollution as five modern cars, used for the same amount of time. And that’s a mower that’s running properly.

One of the largest causes of additional air pollution emanating from lawn mowers and chainsaws is a clogged air filter. If the engine isn’t able to draw enough air, it will run rich (i.e. too much fuel and not enough air for complete combustion) so unburned hydrocarbons are released through the exhaust.

K&N makes filters for riding and walk-behind mowers, chain saws, edgers, blowers, and more

And beyond any damage to the environment, it impacts your wallet as well. An engine that’s running continually rich is an engine that’s headed toward failure. And if the damage is severe enough, the expense to repair could easily exceed the value of the mower. This year around 10 million walk-behind and riding mowers will be purchased in the United States. While there’s no data available to indicate how many mowers are discarded each year because of failures related to poor engine maintenance, you could assume that they’re being replaced by a fair percentage of those new 10 million mowers.

The solution is simple: install a K&N air filter on your mower or chainsaw. K&N filters have a greater capacity to capture dirt and dust yet maintain airflow. Also, once you’ve purchased a K&N air filter it means you no longer have to remember to stop at the hardware or “big box” home store to pick-up a new filter each year. You simply wash and reuse!

K&N air filters for mowers and chainsaw are constructed with the company’s hybrid air filtration medium, which is a non-woven synthetic material and is incredibly easy to clean. Designed to be used dry with no oil required, the filters don’t even have to be completely dry before re-installation. Just spray on the 99-0624 synthetic air filter cleaner and clean the dirt, dust, clippings, and other contaminants with just a garden hose.

K&N Filters are reusable, so they need to be purchased just once. Just wash each year.

K&N also manufactures many direct replacement filter elements designed for small industrial engines, compressors, generators, snow blowers, utility lawn and garden units such as edgers and blowers, industrial polishers, and other auxiliary power units (APUs), with engines manufactured by Briggs & Stratton, Tecumseh, Honda, John Deere, Kawasaki, Kohler, Onan, and others. Some of the most popular filter applications are K&N Filter 33-2238 that fits many Honda engines from 4HP to 6.5HP and many Briggs and Stratton engines from 3.5HP to 6HP. Most Stihl chain saws are covered by three K&N Filter part numbers E-4250, E-4310, and E-4690. K&N also offers air filters for Bolens, John Deere, Kohler, Tecumseh and others.

In addition to the mower and chainsaw filters above, K&N’s automotive performance line includes air filter wraps, clamp-on air filters, crankcase vent filters, plenums, carb adapters, K&N Stubstacks®, carbon fiber composites, filter accessories, air/fuel monitors, inline fuel filters and pumps, diesel fuel filters and air restriction gauges. K&N also offers a wide variety of performance parts for motorcycles, personal watercraft, and boats. To locate K&N upgrades for cars, SUVs, vans, commercial trucks, karts, scooters, motorcycles, campervans, or almost anything with an engine, use the K&N search by vehicle tool.
