Sorry Locopower, I re-read your post and I'm ,..well,.. kind of an idiot for missing that. I just did the Zoodad and used an aluminum mesh to strain the bugs. Apparently this might make for a blender effect with the bugs though and chop em to bits. I think I'll leave it and see what happens. pics are in my gallery.

It surprised me quite a bit to hear it again like that, very shrill turbo whistle climbing into my ears while pulling.
The AIS muffles about 90% of it, leaving just enough to give you that big grin when the engine is working.

Flow for the 6637 is hypothetical. The cfm number is based off of another web site and is not a proven fact. Dyno numbers prove the 6637 out performed the AFEII.

BTW mech, I think everyone on this forum is well aware that you advocate using the big round paper 6637 filter for any and all PSD applications, so there's no need to reply with bold face type!
