Re: Wk intake show yours off. 5.7L

Over the years I've gone through about 3-4 different renditions of CAI's on each of my Hemi's. I have never even considered "wasting" $300 plus for an aftermarket unit, that in many cases doesn't work as good as a custom one made from stock components. FWIW, a stock Hemi airbox is capable of flowing just under 700 cfm of intake air and a stock Hemi, with about a 75-80/% volumetric efficiency is only capable of flowing a little less than 600 cfm through the combustion cycle, so a CAI that is capable of flowing 800+ cfm and costs mega $$$ is totally useless, unless you like to spend money and enjoy lots of noise.

The CAI's on both my Hemi's (LX and WK) are made using LX (Charger, 300C, Magnum) SRT airboxes modified to add a second air inlet, and both inlets draw cold air from the grill/fender well areas....not from the hot engine compartment like some aftermarket units do. The intake tube for the WK is also from LX SRT. Note that it had to be extended a little to reach the airbox, but WK owners can purchase the WK SRT intake tube and it works fine. The air intake tube in the picture for the LX is totally custom and tapers from ~4 in. down to 3 1/4 in. at the throttle body. It is also a double wall tube, made that way in an effort to reduce heat soak through the tube at lower speeds/RPM. Both now also run AFE high flow air filters. I find these CAI's to be more than adequate for my like modified (see signature) Hemi's, and total cost of each was roughly $50 or a little less.

Nice setup (and write-up). What did you use to pipe the air to the air box from the fender/ grill?

Plenty of good info bro. Unfortunately I can't exactly do a modified stock setup. That would mean me putting the resonator box back in and that thing is restrictive. However I still have plans on going to a modified injin setup with airbox and lower pick up ducting.

But as you know I've already raised my VE substantially with a free flowing exhaust and intake setup

I saw what you did to your intake and want to do the same. I noticed there is a plug probably a sensor inside the stock one. What did you do about that?

Re: Wk intake show yours off. 5.7L

If you're talking about the sensor near the airbox, it is the Intake Air Temperature (IAT) Sensor and is essential for proper engine operation. If you purchase a stock WK SRT-8 intake tube, it'll have the hole for the sensor in it. If you make a custom tube, you'll have to make the hole in it. Closer to the airbox gives you a cooler reading (possibility of a little more timing) and closer to the throttle body gives you a slightly warmer reading. To give you an idea, the 05 Hemi LX's (Chrysler 300C, Magnum, Charger) had the IAT Sensor right next to the Throttle Body Butterfly and the IAT temps. would run ~5-15* higher. On my 05 Hemi LX I installed a rheostat wired into the cabin so I could control the IAT. Over the years, I have found that the vehicle seems to run best when the IAT is set about 20-25* below the reading indicated by the sensor. On my WK, on the highway (with the sensor mounted in the stock position near the airbox), my readings are almost identical to ambient in most cases.

As a side note, if you are going to do this, you may want to consider picking up a 392 Challenger IAT Sensor (P/N 5149279AB). It is longer than the stock WK/LX ones and samples air from the center of the tube, as opposed to the stock shorter one that samples air from near the outer wall of the intake tube. The stock one is more subject to engine heat soak, because of its close proximity to the outer wall. Also, if yours is an 05, you'll have to change the black plug over to the gray (later model) plug. The part number for it is, 05014003AA. Hope this helps you a bit.

Where did you get your srt-8 intake tube?

Re: Wk intake show yours off. 5.7L

You can get them from the stealer or try to find one on one of the WK SRT-8 forums. I've read where a couple folks have found them for as little as $15. The one on my WK is off an LX SRT-8, but I had to extend it a little as on the LX the distance between the airbox and the throttle body is about 3-4 in. less than on the WK. I imagine you could also do the same thing if you could find an LX tube somewhere.

Sorry to be such a bother but I've been looking all over the Internet including Chrysler factory and I can't seem to find a thing. Any chance you have a link to the one you bought or a wk srt8 one?

Re: Wk intake show yours off. 5.7L

Not a problem. Have you looked in the "parts for sale" over on the various Jeep SRT-8 forums? Mine was not a WK SRT-8 tube. I extended the length of a LX SRT-8 one for mine, only because I had one laying around. If worse comes to worse, one other thing you can look into (will cost more though) is an AirAid Jr. Intake Tube and/or Tube and Filter......
