i have the airgap. it was the last thing i installed of the mods in my sig. no low end loss. with a little improvement from 2krpms and up. my plenum was not blown when i switched to the airgap. i like the idea of no blown plenum gasket worries.

 

Love my air gap, didn't really notice any low end grunt loss but did notice improved milage and mid range torque. That is with all my mods, far from stock

I have heard from Tim @ Hughes Engines that the AirGap loves PCM changes and will give you a better result if you tune for it. I believe if you dig around their site, they have dyno results comparing stock and airgap with a tune and without.

 

Think I posted this earlier in this thread, but.... Dyno Tests.

 

Hey You! always on top of it

 

What about this Ebay "Airgap" manifold? Anyone ever heard of this or tried it? pretty good price.

No injector bungs.

 

It's funny how that ebay carb air gap always makes it's way to these kind of conversations.

 

Are they junk?

 

Probably not, they just won't work. Unless, you want to go carbed.

 

Its wonderful if you want to switch to a carb setup, theres a reason why hughes charges so much, it comes with the adapters and the fact that they are predrilled injector bosses, the ebay ones dont have the injector bosses drilled meaning you would have to get them drilled and then buy the brackets to set it up to be at the same height as the stocker and be able to bolt up
