I get the same rattle past 2800rpm, so usually doing about 75 on the freeway. Just a constant buzzing, and very annoying. Thought it may have had something to do with the cracked air intake issue, replaced the intake with an aftermarket one and the sound still remains. Stumped, but have a loud stereo, so don't care anymore. Let us know if you find the problem though.
