First I saw these with dyno charts (avail in black or blue) - claims 6HP gain with dyno chart and A/F ratios posted:

then I saw these in blue or red (and you can get all the other matches hoses, no dyno or claim of any HP gain, cheaper, look exactly the same):

Anyone have either one can chime in for comparisons on which I should get? Do the black, blue, or red hoses look best on the G sedan?

 

and yet another choice that will fit our cars:

in 3 colors. Are all these things the same hose with a different logo on it?

 

comment I found from a guy on the370z.com:

>The Z1 Silicone tubes seem to fit better than the HPS tubes, didn't have to trim the passenger side >tube at all, perfect fit. The overall quality seems to be better as well, a bit thicker than the HPS.

 

6HP by just changing the pipe? If it was only that easy.

 

Z1 is a great company w/ excellent service...go with them.

 

I'll probably go with them, haven't found anyone talk about their experience Moshimoto one, except that if you like in PA and have a G37 they'll give you one free if you let them test dyno your car with it.
