1st one...NO
2nd one...Ok, if you take off and throw away the red pre filter.
3rd one... is a sno pod, yes... but not the right size.
Use this part # UP-5182 for stock carbs.
This is a 5" so will have to be squished in to fit.
You can also get the UP-4182, this is a 4". Fits better but I like the 5" for extra volume because they are squished in so much.

Chuck are the pre filters just a waste of time or what? I still have them on my bike. Just curious is all.
I am currently using the 5245 pod, per the old forum when I was looking at getting rid of my airbox.

Do you have flat track tires on your RD and ride in dirt?
If not, you don't need motocross type filters.

Ok that makes sense. :)
Well I'll lose em then. Should improve airflow too.

Thanks
A single tall filter with Y boot is a better option for better power ? Below filter suitable for Y boot ?

Nice thread for those wanting to upgrade to different airfilter that isn't the K&N pod.
I will not use K&N brand air filters.
Many years ago, I had K&N filters on several vehicles, until I found fine dust down the "clean" side of the intake tract. That is how K&N can claim they outflow the competition. I'd rather dirt not enter my engine. Oiled foam filters work better. AFE makes a multi-layer filter that resembles the K&N style, but it actually filters out the dirt. https://afepower.com/nsearch?q=pro+guard+7
