Is anyone running a Thunder Products TPI valve or similar product on thier air box? Looking for opinions on how well they work.

 

I run them on my snowmobiles and they work good. I also wonder how they would work on an atv?

 

They will do exatly what they say, but you are going to have be careful that you do not allow mud and or water to get in you air intake system.

 

So do these mount in front of or behind the filter? I highly doubt I'm going to be successfull at staying out of the water and mud [img]i/expressions/face-icon-small-happy.gif[/img] Has anyone running these come up with a creative way mount em'?
