Does anyone know what airboot twisted development is talking about the in the video? For 80 bucks seems like a stellar deal. I searched the Twisted Development and couldn’t find anything.
Fast forward the video to about 3min 50 seconds when Jaime starts talking about it.

I took it as they were selling the reflash on the stock ECU, that even that modified the stock one worked well?
The Shop
Top is 2018 250/350 - long air passage
Bottom is 2019 250/350 - short
I’m running the 2018, it’s not a game changer mod like put this in and you have a new bike. But if you do all the little mods like screen less filter cage, holes in the air box, airboot, exhaust and add the remap or Vortex from Twisted. YES there is a major difference.
Husky and KTM 250+350 from 2019 share the same airboot.
So I’d assume the advantages would be the same for Husky on all the mods I wrote about above. I’ve never tried them on a Husky, just speaking theoretically.
Bling bling
I use a 2018+ 2 stroke filter cage with no screen.
Guys mod their 450s too, ya' know.
Pit Row
Sorry to revive an old thread but…
I have a ‘22 sxf350 and I wondered if this was still a worthwhile mod for my bike as I don’t have them side by side to compare. Loving this 350!
I've done it to my '23 GasGas. I believe it was around $65 for the boot from a 2018 350SXF.
The 2018 boot has that longer velocity stack molded into the rubber. It adds some low end torque. Like others, I run the two-stroke filter cage (no wire-mesh backfire screen) and I cut the flap off of the inside of the airbox. Also, I replaced the standard muffler with one from a '23 MC250F because it doesn't have that icecream cone baffle.
When my bike was stock I had to dab the clutch in some corners with stock gear ratios. (I am 160lbs)
With four simple mods (airbox lid, air-boot, filter cage, muffler) the MC350F rarely needs the clutch to accelerate out of a corner in map 2.
I've done the exact same thing on my 22 Ex250f and it makes a noticeable difference. Adjusting the TPS voltage helps too.
Used ones on eBay for less than $30 shipped…
Ok! wait a second, what 2018 model KTM has this Carbon velocity stack intake
Thanks. What do you mean here:
“and I cut the flap off of the inside of the airbox.”
I don’t follow. I’ve already got the mesh-less filter cage, a full FMF, the stock ecu is remapped and the bike runs really well coming from a 450. But could always use a little more torque.
I think he's referring to the flat piece of plastic in the finger-grab hole on the airbox cover on the GasGas bikes. Removing that is an easy way to get more air in the air box.
Like FGR01 described...
The back of the airbox cover there's a rib... I trimmed the mud-flap down, but left a bit of the rib to maintain some structure on that panel. (See photo below).
Lots of guys are drilling holes in the cover and there's a vented airbox cover available too.
UFO makes this one:
Got ya!
I’ve got a ‘22 Ktm 350 with both vented and non vented covers. That’s a good idea trimming the seam to let some more air in on the non vented.
My bike has a full FMF, the stock ecu has been remapped to take out some engine braking and I’m not sure what else was done on the tune. I put in a mesh-less filter cage and obviously the vented cover. Bike runs REALLY good and I enjoy it over my ‘21 450. On our smaller tighter tracks here in Missouri it gets around well with the 14/52 but a little more bark would make the bike perfect. I’ve become a firm believer in velocity stack designs since I started using them on my Stand up jet skis (picked up a solid 1mph and a little more out of the hole).
I ordered a used one on eBay for $28 so I’ll report back with results.
Where do you purchase this longer velocity stack (assuming it is for sale to the public)? thx
