Air box bases are cheap. I just cut my box off around the aluminum Pro Design flange and used some aluminum strap to support it. I feel that my filter stays cleaner not having the box to "trap" the dust around the filter. As for throttle response....not much different, but I'm stock bore and just a dumb farmer.

 

I really like my PPD airbox!!!!!!!!!!!![img]i/expressions/face-icon-small-happy.gif[/img]

 

I also run the pro flow with a k&n with no lid. Im also using a stage 2 dynojet kit. Ive seen the turbulence thing being brought up a lot. But my raptor runs awesome,with instant response in any gear at any rpm's. Maybe im just lucky.

 

What is turbulence and how do you know when it is happening?

 

Hold your throttle in just off idle up to 1/4, it will probably sputter if you are having this problem. Most raptors do it a little bit anyway though

 

Surging is a good indicator as well. Old thread we have here.
