Meh
The quality is about on par with K&N, not sure why they cost triple. Oh thats right, the placebo effect of the "Made in Italy" printing on every corner of the box and product itself.I feel zero difference in power. I even swapped back the oem filters and felt nothing. Taking out the charcoal filters appears to be the actual thing contributing to spool up noise. There is also no difference in spool time. So there's that.Overall, seems like a waste of money if you're on stock boost.
