intake with bypass valve?

I heard AEM doesn't have one for the 3, does anyone know of one that does?

i dont think there are any available for the 3 as of yet. look into the wet sock by Injen...the_gray_mazda6 has given some good reviews on the product.

you would be better off with a sock

yeah, basically the same concept, but a sock is too thick and would cut off a huge amount of airflow to your intake thus giving you less power than expected. instead, a pantyhose would work much better as long as the damn thing doesn't rip. but if you want to be really safe in an investment, the hydroshield by injen is the way to go.

you do know that i dont mean the sock on your feet right...i mean like the one on Injen....hyrdoshield...sock same defintion

K&N also makes a similar product called a pre-filter. My friend's and I all use them on our off-road vehicles to keep sand/crud out. They work terrific.
