K&N air filter?

[rboe]

Between what I've learned on the dirt bike forums and the Guzzi forums; the K&N does NOT protect your motor from fine particulates and the stock filter breathes well enough that I'll never buy a K&N again.

Made sense back in the carb days; but not today.

Typically when I respond that the stock system breaths pretty good already folks post in disbelief; then I look at the area of the intake snorkel on my F150 3.5L Ecoboost motor, pretty much the same size as my 1.2L normally aspirated Guzzi engine and I stand my ground. These modern motors breath pretty darn good and unless you affect the whole air pumping train from intake to exhaust and the valve timing and ECU programming all you are doing is giving money to K&N. And probably increasing intake noise.
