About five days ago I installed an AEM Short Ram intake in my 2000 Civic Si (my first mod!). So far everything's worked out beautifully, but there's one thing I'm a little unsure of. The intake produces a steady "ringing tone" that's only really noticeable when the engine is idling and it's otherwise quiet in the cockpit. I can live with it, but what I'm wondering is:

Should I be hearing this sound?

and

Is there any way of quieting it?

Thanks!

 

make sure you didnt leave a tool, or any nuts or bolt in your engine bay.
