KTM airbox cutout

[adamd1979]

I've got an 05 ktm and I was considering cutting out the bottom of my airbox and using the prefilter supplied by timbersled this year. Has anyone had success with this, and if so, what part of the airbox did you remove exactly. Pics would be great. I've tried the pod in the past with mixed performance, but I'd like to keep the boot of the carb intact so the air intake is more uniform.

Yes that works. Just cut bottom of air box off. So there is no shelf for snow to collect. Run the Pre filter. And leave air box cover off.
Works great. Done that on 3 bikes

Air box

Before you cut the air box take a good look at it pretty sure they are two piece on my 2004 and buds 2009 they are .we just took the back half off worked great . If you get any snow build up on the filter just reach back an give it a rub only prob is mounting the battery but not hard

Yep, We have done several that way. Just did another yesterday. Removing the bottom of the box will let snow fall out. Basically just pass through the box. The box won't fill up with snow if it has no bottom. Another little trick is to keep the box and filter "cold and dry". There is a little engine, exhaust pipe, and back wash heat that is warm and "wet" that will accumulate under the seat and on your filter when you stop. When you take off again, the cold pow will stick to everything. I'm sure you've seen this already. We have been installing SLP round vents near the top of the side panels to "evacuate" or let "vent out" that warm, moist air that will gather there when you stop. A cold, dry filter stays super clean all day.

I'm seeing part number 14-189 for this. Do you run a separate side panel in the summer? Do you just clip these in or do you run an epoxy as well?

I'm getting my 2011 KTM 300XC ready for this winter and when you say to run a dry filter would I just get a new filter and run it with no oil wrapped in frogskin?

It has been testing perfectly. Clean and rev's to the moon all day. Lots and lots of air. I wouldn't remove them for summer. Your oiled filter takes care of dust etc. It is letting the warm air "out" of the box keeping things cold, which keeps them clean. No sticking snow on the filter or in the box. The frog skin window is added air in case your filter gets wet or sticky. This is a new test and seems to be very good. It will hold a higher gear and track speed over other bikes. Air equals HP. We only have a small amount of HP to start with. We want to keep all of them!
