Has anyone heard of the Juice Box? It promises increases in horsepower but a search for Juice Box on the forum turned up empty. It sure looks like a cheap way to increase HP but I'm skeptical about quick fixes like these (warranty, insurance, etc.). Your thoughts are welcome. Thanks.

hmm..... the guy who wrote the write up and the quality of the write up ("transmition") leads me to think this isn't a very professional product? I highly doubt if they spent any R&D tuning the thing if it costs 20 bucks.... Also it says it fits all mazdas like rx7 and 8s but it DOESN'T work with turboed cars, but yet the tunings of NA 7s are quite different from 8s I think...
but then again 20 bucks doesn't seem too much for a try....
I'd recommend getting a filtermag for your 20 bucks instead :D

 

It does seem a little too good to be true, and I wouldn't want to screw something up if the product is indeed sub-par. What do you mean by a 'filtermag'? Is that one of those high performance filters (ie. RoadHog)? Thanks.

a powerful magnet that attaches to your oil filter. Traps a lot of metallic particles that regular filter can't filter out (down to 2 microns or something).
