Crawford Plenum Install
I just installed the new Crawford Cast Plenum. I just followed the instructions and the install went without a hitch. I chrome plated the Crawford strut bar. A little eye candy never hurts!! What took the longest to do was to trim the OEM plenum cover. After triming the cover I used black door edge trim to finish off the edges. I can really tell the difference at the higher rpm"s. Great mod! Enclosed are a few install pictures.

As we have been talking to people about the install, it has become obvious that there have been problems with the install / install document. The main issue is a bracket that is located on drivers side in front of the lower plenum. It is stamped with the label "M3" (Go figure). This bracket has been getting caught between the upper an lower plenum and can cause a leak. The instructions have made it more clear with descriptions and pictures, but basically the skipped step that needs to happen is the removal of this bracket. All it does is hold a wire loom. New loom brackets are included.

I disconnected the battery for 24 hours and I'm gettin some wierd idle. It idles at normal rpms but seems to be bouncing up and down very slightly. Also when i drive it for more than 5 minutes and come to a complete stop the idle goes below normal rpms and the car almost seems like its gonna die. What else can i do?

If you did, I bet you need to go through the idle air volume learning procedure.

i have a hissing noise from the front left side of my plenum i dunno if its the plenum (which i highly doubt because i torqued the crap of the bolts and its as tight as prossible) or is there something over there that makes a hissing noise thank you!
also i didnt have a leak for the first 2 weeks i had the plenum then it reared it ugly head today so i suggest everyone checks the plenum or just do the fix from there website

If you torque the crap out of the stock bolts the heads will eventually pop off and you'll have to drill them out. If you are hearing a hiss from general area of the plenum (i know, it's hard with all the ambient noise) spray something like VandyZ said or run your hand over the area.
As far as the M3 bracket, I chose to leave it in place but just grind a few millimeters off the edge that was abstructing the plenum. It took about 30 seconds with a Dremel but you could use a regular file too.
Throttle body connector - I have removed this wire and not had any problems. However an idle relearn won't hurt anything. If you can't figure it out, Nissan techs can do it in about 3 seconds the next time you go to get your oil changed.
Overall I'm happy with the new plenum as well. It was a little more of a hassle than the previous ones, but it's certainly worth the effort as it looks better, and probably doesn't flex at all.

If you do take it in and let Nissan reset it with consult, base idle has to be restored to factory before Consult will let you relearn idle air volume. So if you do have your idle raised as many of us do, be sure to let them know. Also make sure they put your idle back to save yourself an extra trip back to the service dept.
