Anyone in here have any real world experience with the Hughes/Edelbrock Airgap kit? I was planning on going ahead with the Plenum repair, but stumbled across this kit instead and was intrigued.

Let me know!

If you are referring to the FI Airgap intake manifold, many guys on here have it. I will let them chime in, but I can tell you right now, they pretty much all like it. No where near the MPG claims Hughes gives, but definite power increases.

Another option is the "kegger mod." If you look in the FAQ, you should find that there. Almost as good as the air gap, and definitely cheaper, especially if you do your own labor.

There might be a lil mpg gain but nothing outstanding. Easy install if you just take your time. Get new o rings for your injectors. I power you gain is amazing I love mine.
