I'm glad that worked out for you VOLDAR.

It's amazing how much different (quieter) the sound is when the MAF housing is properly suspended from the heat shield. I didn't mention this benefit when I originally did the mods, but the benefit is real. Just that little bit of contact that the housing has with the shield it has out of the box makes a world of difference.

It is a shame that K&N has done nothing to fix that issue, or at least they haven't contacted me about any design changes.

I'll try and post some videos with it on traffic. I am still undecided about it. It IS LOUD when at WOT and this is something I have to deal with it. I give it another 3-4 days of test and if I decide not to keep it, it will be on the site for sale.
The difference in sound at a given throttle position seems directly related to engine load. If you load it up at 2K - 3K rpm, it will "moan" a bit, especially when loaded with A/C on. Give it a while and your driving habits will change slightly, and you'll be able to avoid the moan. If you're anything like me, you'll become really attached to the "wail" from 3.5K RPM to redline @ WOT!
