Post subject:  CAI question

so i put together and installed a custom CAI using 2" PVC last weekend, running it from the side of the intake box to the front of the grill.

I was wondering which would be better

1. let the air continue to flow in through the stock intake + the pvc intake (probably the best flow but maybe a mixture of cold and warm air from each.)
2. block off the stock intake so it only sucks in from the PVC ( maybe more restrictive air flow but only cold air getting sucked in)

i tried both ways but wasnt able to decide which seemed better, havent tested MPG yet. kinda seems like leaving them both open works better but its one of those things where it could just be in my head lol.

anyways what do you guys think?

I'm working on an intake mod using ABS pipe elbows instead of the flexible downspout.
I have already fitted it together, and it doesn't look like an add on. I have fitted the end that goes into my airbox with a threaded plug so that I can seal it while off-roading or it is too wet out. Now I need to determine the best way to permanently attach and seal it.

I'll post pictures, a parts list and a how-to in the fabrication section when I get the time to install it.


I finished my install on christmas eve. The parts that I used are all 2" ABS street elbows as follows:

1 - 90 degree elbow
3 - 45 degree elbows
3 - 22.5 degree elbows
1 - female threaded coupling
1 - threaded plug
ABS cement
Black RTV silicone

I first removed the grill and the airbox. After determining the best fit I assembled the 90, 45's and a 22.5 elbows to form an "s" to come out of the side of the air box and go around the radiator support post. It should look like this when assembled:

Using a 2 1/2" hole saw, cut a hole in the side of the airbox:

Also cut a hole in the rubber behind the grill just below the headlight for the pipe to go through. The second 22.5 elbow goes through here into the "s" pipe. Make sure to aim it forward like this:
Image

Reinstall the airbox and fit the pipe into it so that the last 22.5 elbow can fit on it to direct the air up toward the filter. Then install the female coupling to be able to cap it off in wet conditions.:

Once it is all installed, make sure to seal around the new intake and the box with the silicone to keep any unwanted water out. Reinstall the grill and it should look like this when it is finished:

I really like this set up because it is hardly noticable and almost looks factory under the hood.

i basically made this setup but used PVC spray painted black because i couldn't find any black pipe.
