How hard is it to install? Is it still possible to advance the timing?

Any noticeable benefits? All other feedback would be greatly appreciated

Here's a pic I nabbed off H-T a while back (dunno who it belongs to):

 

ask AJ PwR

 

Does anyone run the M's Intake? If so, how do you like it?

 

Ah...shoulda guessed Ben would be using it

 

i will be running this M's cleaner

 

Thanks to Ben (AJPwR) for his insight

I'll post some pics if I decide to get one
