'05+ CAI Breakthrough....Finally!

[canes5time]

Yes thats right. You read it right. A Cold Air Intake for the '05+ 4cyl Frontier. Nissan tried and failed to keep a CAI off the 4cyl's. I have overcame the garbage intake that is molded into the intake manifold.

I've been working on one, off and on, for over a year and a half. Tried a couple different setups. All threw codes on the Scangauge II. Mostly the "running too lean on bank 2" code. Those codes would usually come in the first 2 to 10 miles after installing the CAI's.

The CAI I have on my truck has been through over 500 miles of city and highway driving. Not a code, stall, hesitation, hiccup, or burp. Smooth.
The engine is running as normal, but with alot more power (butt dyno) and a deep, throaty sound.

I was just wanting to know if there is anyone interested in the details on this project of mine.

An interesting question....how does a 4cylinder have a bank 2? does it run 2cyls per bank?

Sorry. The code was p0171. "system running too lean bank 1"



Here are some pics.


This one is the front view...


From the passenger side...


From the drivers side...


I also made 2 brackets......bracket 1


bracket 2


close up of bracket 2 thats mounted under the ABS........


I also am getting together a list of materials for you guys. So you can attempt to build your own. Or have it built for you.

Thank You!!!!!!!!!!!!!!!!!!!

I'll start from the throttle body and go to the filter.

1. 1 2 3/4" to 3" coupler. Like this one. I had this.

2. 1 3" vacuum adaptor. Like this one. I bought this at Autozone.
This comes with a plastic coupler. I will relace the coupler though.

3. 1 90* elbow. Like this one. I bought this at Autozone.

4. 1 4" straight tube. Like this one. I bought this at Autozone. It
comes with a plastic coupler. I will replace the coupler though.

5. 1 3" universal coupler. Like this one. I had this.

6. 1 Mass air flow sensor tube from an '04-'06 2.5l Sentra or Altima.
I bought mine on eBay. The good thing is the tube comes with the
sensor. These are expensive. The seller I bought mine from has 2
auctions right now. This one and this one. $39.95 + $8 shipping.
The good thing about this is the sensors are the same as ours.
So we can have a spare.

7. 1 MAF tube filter adapter. Like this one. I used 2 1/2" bolts and
2 1" bolts to secure it to the MAF tube. The 1" on the bottom
for the brackets.

8. 1 Filter. Make sure it will fit on the sensor tube adapter. I used an
AEM Dryflow. Like this one.

9. 2 Custom made brackets. I used some 1/4" x 1" flat steel. The
bottom one was 6". The side one was 9". I just bent them to fit.
2 nuts to secure it to the MAF tube. (see #7) 2 bolts to secure it
to the truck.

10. 2 Rubber grommets. I used these between the brackets and truck
body. To give the intake some flex and dampening.

Good luck to all. Post some pics when you get it done.


*The only problem I can forsee is the MAF plug on your trucks. On my first try at a CAI, I extended my wires by cutting and soldering about 10" of extra wire to reach. So, I'm not sure if your wires will reach where I have my MAF tube. They are packed in a track behind the rubber tube on top of the motor. Make sure you look to see if these will reach before doing this. You may have to extend yours too or put the MAF tube closer to the throttle body. I apologize for not remembering this sooner.

has anyone else tried this as canes5time described? (thanks by the way) How did it go?

hey Canes... This is my current setup.. Do you think i would gain any more power with your setup? Inside the filter box, i cut my stock filter to the rubber, and basically used it as a gasket

More power? I couldn't tell you that. But cooler air? Yes.

The sound is awesome isn't it.
