i have a tenzo R filter and i was wondering how to change out the whole intake and put in a cold air pipe. i couldnt figure it out because of all the little tubes going all over the place that were connected to the stock hose conecting to the mass air sensor.
Help Please!

heh, prepare to be egged, that's funny!

It's not that difficult.

First remove your Tenzo filter.

Then remove the MAF from the air tube.

Afterthat you'll have to rmove two screws that hold the resonator to the bracket that supports it.

Then remove the vacuum line from the air tube. It's not hard to spot. It'll be halfway between the Throttle Body and where the MAF was.

Diconnect the hose that connects to the valve cover.

Then you should be able to remove the air tube and reasonator in one piece.

It's easier than it sounds. Just take your time.

After that, pull your front driverside wheel. Then remove the clips that secure the fenderwell liner to the fender.
Pull the liner back, and you'll be able to get at the other reasonator.
Remove that and you'll be set to install whatever intake you desire.

thanks for the help, but *** about the little tubes that connect to the old big tube. or are they not important?

All the tubes (with the exception of the resonator tube) should connect to your new intake. PRI, HotShot and AEM CAI's have fittings for the vacuum lines and the other tubes.
The cheap "offshore" brands may or may not.

thanks for all the help. i will definitly try it out. i just have to get the tube .:D

Please let us know how it turns out and if you feel any power gains :D We're all still in hot debate over whether the CAI for the NX makes any power.

Everyone says, "oooh it should. The 200SX is similar to the NX2000. They both are in a sealed area. The 200SX responds to the CAI great." But I have yet to see a dyno chart on a NX2000. Besides lok at the MPH and 1/4 miles of cars w/o a CAI.

I was going through the "running rich" archives tonight and found this quote
from ianshannon that pertains to a cold air intake setup affecting the a/f
ratio:

"Jim Wolf also agreed with me that the MAF might be
miscalibrated by the rush of air, in turn becoming confused and running
too rich. They also tell me that running the POP with the maf to T/B
pipe will not hurt and may bring back my top end."

If its true that a CAI setup can screw up the MAF readings and cause the car
to run rich, is there any solution to that problem that will allow one to
keep the CAI and not run rich?

Something I was looking at in the archives from last year. Just interensing

Here we go again.
Besides lok at the MPH and 1/4 miles of cars w/o a CAI.
Son of s Skylin-Thomas Fox etc.
First off, 1/4 mile times aren't necesarily an indicator if the CAI's work for the NX or not, as there are other factors that come into play.
And I don't drag race, hence no 1/4 mile times on my car.

"Jim Wolf also agreed with me that the MAF might be
miscalibrated by the rush of air, in turn becoming confused and running
too rich...."

How long ago did this conversation take place? A lot has changed since then. I recently emailed Mike Kojima about this subject of CAIs on an NX vs a CAI on a "Classic" and his answer was:
"CAI's work the same on both cars" .

I have said it once befroe, and I'll say it again, I am willing to do back to back comparisons on my NX at the next SoCal-SERCA Dyno Day!
And I'll post the results here on this forum!

That conversation was back in I think 98 or 99. They completely hated the CAi concept. But then again they were selling POP's at the time.
BTW, HURRY UP WITH THOSE DYNO RESULTS!!!!

Sweet! Can't wait for the results so we can figure this out once and for all.

SoCal-SERCA won't be having another Dyno Day untill early next year at the earliest! Gotta give everyone a chance to finish installing their mods.

God our cars have been out for 13 years yet know one has any proof that cai work? Unreal. I wish some one knew I would hop on that gruop buy for 150.00.What ever happened to the shorty INJEN it made good power on project SE-R. They don't list it on there site?:mad:

Just about ALL of the testing has been done on either "Classics" or the 200SX SE-Rs. To my knowledge, no one has done back to back testing on an NX2000.
However, the consensus from the SR20 Guru's, Mike Kojima Rob Cadle, is that CAI's work just as well on the NX as any other SE-R.
That sentiment flies in the face of the prevelant wisdom here that air can't reach the air filter of a CAI mounted in the fenderwell of an NX2000. Therefore a CAI equipped NX2000 won't be able to breathe at high rpm's resulting in lost HP.

YEAH RIGHT :rolleyes:

This is why I'll be more than happy to put this controversy to rest. And submit my NX to back to back Dyno testing at SoCal-SERCA's next Dyno event.

It was my understanding that it was a "one off" peice made just for that car, and not a production model.

Hey, I resemble that!!

And to add to the debate, I recall hearing that it's not necessarily the cold air or the "improved" airflow of the CAI that makes more power over the standard underhood intakes, but it was the length (and smoothness) of the intake piping that helped provide the "edge". Something to the effect of resonance... Too technical for me to explain.

Hey! Stop picking on me. :(

I wanna see the Place or HS intake dynoed with a AEM filter. Please keep that in mind. That may bring the numbers even closer.

Naji Dahi (http://www.geocities.com/n_dahi/) has a very good explanation of how a CAI works.
Recommened reading for anyone who doesn't know(or already thinks that they do) how a CAI really works.
