are these two a good combination on a z400?

 

the proflo helps out a prettygood amount on lowend and the Yoshi is one of the better pipes out there so yeah its a good combo

 

Yep they are a good combo. That is what I originally had. Make sure you get the jetting right though!

 

what do you have now? the prodesign? what's the difference? i'll get the best

 

Depends on your riding conditions...

1. All dry areas like dunes and deserts and trails with little or no water to enter the airbox- K&N with adapter (I say it flows a little better than the foam)
2. Some wet areas but all around good for everything- ProDesign with adapter

Both filters are excellent so let your riding conditions determine which one you get. [img]i/expressions/face-icon-small-happy.gif[/img]
