Engine Husqvarna YTH24V48 - K&N Air Filter

Going on 7 years now with the K&N air filter for the Husqvarna YTH24V48. Still going strong, no problems with the filter. Clean, re-oil, done. Saved money in the long run. Annual regular oil changes, probably could get by without an oil change every year because the oil stays pretty clean towards the end of fall, but I change it anyway. 😚

RU-0160 - Universal Clamp-On Air Filter. (You don't need the clamp, it fits perfectly!)
22-8009PK - Air Filter Wrap ("Pre-filter" Helps keep out larger debris from the filter. Suggested!)

You can look for your specific Lawn Tractor here.
You can use their search by dimension feature to find a K&N filter that fits your tractor if yours is not directly listed.

KN filters were designed for racing. High flow and catching large particles. I've seen many tests that show it lets significant dust and small particles thru. On an engine that sees a lot of dust, it is an engine killer according to many posts. Go to 18:30 for final results on air filters he tested. KN was next to dead last on catching small particles. It was first in flow. The only thing that beats it is no air cleaner at all. In other words no filter flows more air than it does, and catches less.

7 years later, I still don't care what you or any other K&N haters think. I think its hilarious. I come on here to tell you about a true testimony now of 7 years and still no problems. I change the oil annually so your big particle theory is pointless.How much have you spend on filters in 7 year, 10 years? More than me. :LOL:

and I don't care what you think anymore than you care what I think. People have a right to the knowledge, and they can decide what they want to do with it. I used KN filters until I got tired of dirt getting into my engines.
 
Come down to South Texas where the weeds grow better than any grass.

You must have a textbook yard to cut and no droughts to endure.

I've seen this same "armchair science" used many times on ATV's and UTV's for years.

Adding a high flow engine air filter to anything working in a dusty/ dirty environment just shortens the life of the engine.

I am baffled how people can think that they are improving the OEM design, fit and function by using over advertised aftermarket parts.

Those "high flow" K&N branded air filters are (cleverly) designed for operation in clean environments like a warehouse forklift or an in-door go kart racetrack.

What I see in this situation is an engine on a mower getting "dusted" internally and eventually earning the name "old smoky" because the valve guides, cylinder and rings have been ground beyond tolerance by silica dust.

Eventually adding oil and changing oil fouled spark plugs will become second nature. The engine oil will turn to "black mud", and the engine will gradually lose power when under a load.

If a K&N works for you, that's great but you really should include "the rest of the story".
