Throttle Body Spacer Question

huston said:

I was just wondering what exactly the throttle body spacer does.
It claims it gives 2-4 mpg as well as 5 hp....any truth behind this?

If anybody has purchased one, what are your feelings about it?

Thanks,

I dont know if I ever got any better gas mileage,probably becasue i didnt try and see if I was or not, hp wise I noticed a bigger diff with the helix spacer than I did with my 77 series intake from k&n, driving wise I thought I could feel more of a difference.my intake is supposed to give 7.25hp est. everyone has diff opinions.Some ppl like them some dont.Also the helix makes a decently loud whistling noise up to around 2500 rpm

I had the k&n 77series intake,rated at 7.25 hp put a helix tbs a month or so later and felt more of a difference with the tbs than I did with the intake. How odd can that get lol
