Has anyone done this on their truck? I don't want to wing it and get the fuel air mixture wrong. I got the 4.7 and it just has no power. I'm planning on getting headers at some point too, and I got a flowmaster on too. The flowmaster maybe gives you like 1-2 horsepower I'm guessing. I'm just looking to get more power out of the damn thing...

 

A cold air intake won't adjust your air fuel mixture. That's what the computer is for.

 

I did this with my old '98 Durango years ago. I used PVC and a rubber joint to get the intake further towards the fender. I then put a large K&N filter on the end. It definitely made the truck sound cooler and seemed to have a bit more power but it's pretty subjective. A couple of thoughts:

• Make sure you secure the PVC on the filter side so that it doesn't move around. The K&N filter will get damaged easily.
• The PVC can get warped over time from the heat of the engine.
• If you really want true cold air induction you need to get the filter further down into the fender and block it from the hot engine air. My '99 Shelby durango has the filter way down in the fender and blocked off nicely.

 

I'm told the headers aren't really worth it? I don't have them so i can't confirm. I do have the home brew cai and to me i seem to get less pinging and just a hair more power. Idk if sucking in the hot air was making it ping but it seems to have stopped.

Would there be another sort of tubing to use that doesn't warp over time? What did you use to block off the filter? Just another piece of plastic? Btw you're lucky you got a shelby, those things are rare as hell and gorgeous trucks!
I'll have to

 

And I'm not sure about the headers, I know they will change the tone of the exhaust note. I'm not sure why I want to trick out a durango, maybe I want to be different lol. All I need is some 31s with my t/s lift

 

Yeah, I watched for a long time for a good deal on one. I drove my '99 for 10 years and have had my eyes open for a Shelby for the past 3. Found a low milage one on ebay and then offered directly to the seller.

Honestly, I don't think you will get much benefit from the pvc route unless you can get air from outside the engine bay. On the shelby they just used a long stretch of the normal flexible hose that connects the TB to the filter box. This is then routed into the driver side fender and then the filter is connected down there. This probably wouldn't be too hard to do on a stock setup if you can get through the fender.

 

Yeah, I'm not sure if I want to do it. If there isn't that much gain from it it isn't worth the hassle and money. I mean its a 4.7, there ain't much more I can squeeze out of that thing

 

headers on the 4.7 are not worth it unless you plan to build it up VERY big (500+ hp big)

i did exactly that, i replaced the stock tubing on the air intake and fed an intake out the grill to get cold air in.

 

You can problably take your durango to a reputable exhaust shop and redo the Y collector that ties the engine to the cat. the Y collector tube is small in terms of diameter. Have a custom made Y collector with a much larger diameter may help improve your power curve.
