Ulmer racing Airbox Mod for Apex

[the Wolfman]

Has anybody explored this?...yes it's a loaded thread...don't know what to do yet and am wondering if anybody else has had had dealings...

[Master of Faster]

I know that there are gains to be had by modifying the Apex air box, and I have heard nothing but great things about Ulmer racing.

It works for me, tunnel dump exh, and screened vents, I get no bog in powder like I see complaints of on SW.

They are great to work with. They have been racing and working on snowmobiles for a VERY long time and they know how to make stuff go fast. I used to race against his Dad.
