I installed a AEM Brute Force intake this weekend. Install went great, the looks are good, picked up a bit of power. The problem is, at a certain RPM range ~ (1700 to 2200) and a certain engine load ~ (empty truck 30 - 50% acceleration) there is a godawful noise coming from the intake/engine bay. I know that intakes can induce more noise, but this is way too much. I had an AEM certified seller ride in the truck and he called the tech support line, nobody can think what it could be. Any help would be appreciated.

Thanks

I am having the same "vibrating drone" with my new S&B intake.

 

Sorry to hear that. I plan to pull the intake if I can't find a way to stop the drone. Does anybody have any good ideas?

 

Amen. I have this same drone with my S&B. I have to keep it under a certain rpm point all the time.. As soon as the drone comes in, i let go of the gas a tad and it goes away... really annoying.

For me, tends to be worse on hotter days. It's always there, however, more so on hotter days.

 

I don't know if its the same sound your talking about but my AF1 3'' when I down the gas at certain RPM's (usually entering a highway, ect.) it gives off this extremely deep roar...

But I like it.
