My new HPS post MAF tubes installed

Agreed, but most of the gains are in the exhaust dept, the intake is pretty open as is with a direct cold air feed too. I've seen Stillen intakes make 6 hp up top and lose midrange so I do not see 12whp for just tubes at all.

5whp is believable though.

I just posted my results on the same dyno where i got my baseline. Outside temp was about 70 both times and oil temp was about 180...Did 3 pulls after my mods (hps + AFE filter) and all 3 pulls net 285rwhp. the 370Z seems to be very consistent. I just got my ART pipes installed awhile back and waitng for my dyno here hopefully this week. If you cant believe 285 from 273, then i wonder what you will feel like when i break 300 with these pipes...am just being optimistic

panel filters, plus tubes, plus the ART pipes (which seem to make a little more power than standard TP's) and even a Y pipe should get you in the upper 290's -- close to 300 on a dynojet... so... yeah, probably.

I don't know if you'll break 300 without a tune using SAE correction, but you should definitely be in the ball park.

Oh, and 10-12 for high flow filters AND the tubes, is definitely believable.

Yeah i hope to be at 300 + - 5rwhp...kast had about 296 with what i had plus a ypipe...either way i will do a full report with dyno and TQ readings this time.

I finally decided to install my HPS tubes today and ran into some problems. The left side tube fit just fine and all hook up great. The right side tube would hook up to the air box and the intake just fine but the alignment of the little plastic box would not line up at all. I could get it hooked up but then it puts a bad kink in the main intake hose. I tired both tubes and same problem on the right side.
Both of my HPS intake tubes are exactly alike. Is there suppose to be a right and a left? The tubes came in separate plastic bags with different part numbers on them, but they are the same. I worked on this project for two hours (most all of that was scratching my head) which should have taken 15 minute for the whole thing. Bottom line is that I didn’t like what I saw so put it all back to stock.

They sent you two left side hoses. The hoses are not identical. When installed, the HPS logo is on the top of both hoses, even though on the left side the logo is hidden under the tower brace. I would definitely call them. They screwed up and should send you the correct pieces with free shipping.

Yes I think you are right. Both hoses have the HPS logo on both side of the hose. (two logo's a tube)
