Mule pro fxt air filter upgrade

Hello I just watched a video on YouTube by Hesters Motorsports about a air filter up grade for the FXT basicly you use a air filter for a T-rex didn't know this was a problem but they said they have been having some engine failures because the stock air filter allows to much dirt into the engine. Just thought I would pass it on check out the video on you tube. I think I will be changing mine over to the T-rex air filter

Interesting. I didn't realize that people are having a problem with engine failures due to the air filters. I wonder why Kawasaki doesn't just use the Teryx filters as oem? Can't be much cost difference.

Here's a link to the video

Video link didn't work but I found it on YouTube. I appears to me that the problem with the original filter is only a problem if the filter isn't changed until after it's plugged and the engine sucks air past the foam gasket. The fact that the gasket will fail at this point is a design flaw.

I have a new original filter and check mine regularly, so I think I'm Ok. Having said that, I'll buy the Teryx filter as a replacement because it has much more surface area.

UNI is $30 off Amazon.

Not bad for a "Lifetime" filter.

It’s hard for me to believe this is an issue. Donelson filters are top notch. They’re used on a lot of heavy duty equipment, tractors, zero turn mowers. If a person uses any amount of common sense there won’t be any issue with any type of air filter.

The filter shown for replacemt should let more air in but intuitively it seems it would let more dust in. Am I missing something here?

I’m not knocking the filter shown. It will perform differently from the Donelson with pros and cons. But to me it seems very naive to think it’s better for dirt/dust.

Please feel free to refute my line of thinking. I’m open to learning something here.

I was thinking the exact same thing. We use these type of filters on all of our farm equipment (combines, bailers, tractors, harrowbed). It seems strange that if the Teryx filter (11029-0025) works better on the Mule, why design two different types, including having to design and manufacture the inner housing that seats the filter into the box for the mule, when it would be unnecessary if using the Teryx filter?

The mule is a working machine, the Teryx is a play machine. Maybe that's why the different filter.

Is the Teryx filter able/intended to be blown-out and cleaned regularly? I have no knowledge of that filter.

Something is off here...but I would sure like it if Kawasaki would send out a TSB to Mule owners if this change is needed.

No refute from me.
Sounds like the crappy foam seal failing (not the paper filter).
Personally I trust a paper filter with a good rubber seal (like a Donaldson) more than the foam filters
