A part on my bike is somewhat of a Gladiator. If it is on my bike it means it has lasted the abuse of riding, racing, the elements, the unknown. It means that it has bested other products in that space and is in some way, superior. My current race bike is a 2018 KTM 300 XC-W Six Days. 

Everything I run has been carefully chosen and tested in some very harsh conditions. I am proud of, and believe in, the parts I run. I ran FunnelWeb Filters before being sponsored by them. I reached out and asked for the support because I wanted to run the best filter for my riding. They are a sponsor but they did not pay for these thoughts.

This is my filter after race conditions for ~12hrs and still running strong. The pyramid foam traps the dirt & sand on the top layer leaving air still able to pass. Said another way, it prevents the dirt from penetrating deep into the filter. This keeps maximum airflow and makes it much easier to clean. Dual-layer filters can trap the dirt between layers and that's what makes them very hard to get clean again. It is easier to oil this design & resists dripping. I've tested them against regular filters and the life wasn't even close to Funnelweb filter life.

This was side by comparison. Equal time of spinning laps in the super dusty summer. I even ran some dust socks on the twin airs. What I found is that nothing gets past the funnelweb filters. So that's why I run them. I have tested them and seen the performance advantages for myself. 

I need filters to last for 2 day races. Rarely do I need to change filters between days. Every time you take the filter off your bike some dirt gets in no matter how careful you are. If I don't have to remove it, just another advantage. Not popping this thing off in the pits is one less thing to think about. 

The filters I use will get soaked, frozen, muddy, the list goes on of what Hard Enduro races demand. Destry Abbott (10x desert racing champ) & his crew run these, Honda team out of Australia runs these too. Hell, if they're good enough for Geocomo Redondi (2018 WORCS champ) they should work for me. It was designed for combating the dust. They are quite popular in Europe and Australia because of how brutal the conditions are.  

I think of it this way- I expect my filter to still perform even if I lose the airbox cover. I trust the seal of the fwf filters to hold in these conditions. 

These fwf filters have proven themselves and earned their spot on my bike.

I replaced the stock Twin Air with this ProLine Air Filter by Funnelweb. One key difference is that the Twin Air doesn't use a rubber grommet in the center of the filter and KTM air filter cages are notoriously pointy. Some have reported that the cage has worked its way through the Twin Air filter causing a hole. In contrast, the Funnelweb filter has a robust rubber grommet that completely eliminates this problem.

The curiously shaped cones on the Funnelwb filter are designed to greatly increase the surface area of the filter (as much as double) without increasing its overall size. This design allows for greater dust holding capacity while still maintaining filtering efficiency and performance.

The filter appears to be well built and it fits the stock KTM filter cage and airbox  accurately.

The filter has the potential to increase run time before clogging with the added surface area....

But...

It does most assuredly NOT have the ability to increase airflow if compared to a clean standard foam air filter...

The pyramids compete for the SAME outer foam dome diameter as would a regular dome shaped filter... 

The only way it would increase max flow potential is if the added surface area all had its own discreet air path to the inside of the filter as in a pleated gauze/ KN style filter... In which the inside and outside surface areas are virtually identical...

Worth it for extended time until outer surface is clogged... Not worth it if you are purchasing for max flow advantage....

The advantage would be at the point a standard filter was beginning to restrict... The added surface area of this one would not be at the same point of clogging...

So far I'm really pleased.  Got a notoil cage for it. Replaced a Uni.

Seems to be a good durable filter.
