The AEM test results I have seen are not good. Even worse than K&N on one or two. I've gone from AEM and K&N to WIXNo judgment except on the filter. If you want to move away from factory style, get an AEM Dry Flow. Stay away from K&N unless you don't mind dirtier oil. And absolutely a no-go in dusty environments.
Agree and agree. Axle-backs are a waste of money.Honestly I'm a bit disillusioned by most axle-back solutions. Since they won't gain much power and we're just doing this for sound, they seem like an expensive way to get there.
But whatever you do, keep a resonator on it.
