Has anyone put this on? Any noticeable gains?

not on a hummer, but i wasted money on one for my old 4runner. they're worthless IMHO.

 

DITTO!

 

OK, All I know about them is on Mustangs. Supposedly they do give some gain on a v8 but on a v6 they didn't.

Thanks!

 

TRUE

 

Thanks Dilo, that makes me think I wouldn't have a conclusive answer about the h3 unless I'd found someone who's specifically tried it. hmmm...

 

if you can find a place that will take it back, it would be worth trying it out, that way you would know for sure. those threads cut into the inside of the tbs won't do crap. you've already got a ton of turbulence in your intake, adding an extra inch for the air to travel isn't going to do much. although i personally doubt the benefit (from past experience on other vehicles), others here have seen a benefit from the new intakes from K&N and other manufacturers. i think that would be a better investment.
