every cone filter is basically the same
with a k&n youre paying for a name. the drop in filters are ****. we've dyno tested k&n drop in replacements on numerous cars, they lost power vs/ stock. I've also had a few k&n's fail on turbo apps, having been sucked through the turbo, same for the hks foam style.

you're just a typical ignorant brand name nut rider so just gtfo


AEM makes one of the best filters
