just read through this thread...please tell me people don't actually think the engine moves enough to mandate rubber tubing. That is possibly the most assanine thing I've heard...if you're engine were moving that much you have bigger problems than what kind of tubing.

Yes, they are ribbed to create a turbulant flow, but I agree that it is all talk. However, the mixture is not always perfect...that is quite an assumption

i don't understand why you'd replace the tube?

lots of people with the 1st gen G35 would replace the tube with one from a 350z since that one did not have baffles. hence louder sound from the 350z tube. perfect for people combining i with a jwt pop charger.

in the case of our 2nd gens... don't think there is any benefit at all.

anyone else order the cobb tubes?

I'm getting closer to buying them.

cost and flex are two of the three reasons the factory maf tube has ribbing. The other is to slow the air flow and cause a disrtuption when the tb is closed fast to prevent the air from slamming into the tb butterfly and rebound back-flow into the maf causing a/f ratio issues -lean/rich. It works agains the smooth flow more hp factor but helps drivability issues or harsh downshifts, etc. The maf cal. is used for trany shift psi., rpm etc., as well. Most cars that have a hot wire maf have this type of tube. However, it just has become ind. standard and on the 3.7 may or may not cause issue. I know on my 00' Saleen this caused all kinds of false a/r readings. Did it cause a "problem" is a diff question. I think it works more toward the EPA concerns these days and fuel saving rather than a perfomance issue. MFG. can program the ECU to ignore I would assume so... that's my understanding anyway.
