Anybody here put a cold air intake on a SD with the 5.4L engine? I was looking at them online the other day, but would appreciate any info that can be shared. Main questions would be as follows:
1. What brand did you use?
2. Did you have any noticeable gain in mpg?
3. Any noticeable gain in power/responsiveness?
4. Where did you get it and how much $$?

Thanks in advance for any info you guys can pass along!

 

Check this out it helped me alot http://www.duramax-diesel.com/spicer/index.htm

 

The only one I have seen for the 05-07 5.4 is the the K&N 63 Series FIPK.

K&N part number 63-2570 - $261.99 plus shipping at jegs.com , but probably cheaper somewhere else..

I've been considering one, so I am also interested to hear any results.

 

i have the K&N and like it a lot. i first put it on with stock exhaust and noticed a bit of difference but i really felt it when i opened up the exhaust.

 

What about fuel mileage?

 

Well, this is a good start, but there must be a few more folks out there that have a CAI on the 5.4L.

 

Is this it?? Is there really no one else out there with a cold air intake on the 5.4L engine??

 

Save your money. There's no real proof of any gains. If you want more noise get one..
Stay away from K&N they let dust through.

You might want to expand on that - personal experience, etc. in regards to power gains and letting dust through (this has not been my experience with these on gas engines - perhaps they weren't properly installed if this happened).

I will be putting a K&N 63 Series Air Charger on my '05 5.4L 3V within thirty days and this will be the third one I will have installed on my personal use vehicles.

When installed correctly, I have found my oil to be cleaner after using my K&N intakes at oil change time. Always better flow and very little noise unless you put your foot right into it. The gains are noticeable. Significant enough power increase to the rear wheels that you will feel it.

In addition, you will also gain significantly more if you mate this with a tuner and a better exhaust, but the K&N gains are real and as far as I'm concerned a whole lot better than OEM at keeping the dust out (and I drive in a dust bowl over 50% of the time).

I don't have experience with them on diesels if that is what your comment is referring to, but the original poster has a 5.4L gas engine.

 

If you read through the test at the link that pf350 posted-http://www.duramax-diesel.com/spicer/index.htm, you'll see that the K&N didn't score very well for filtering,
but did very well on the air flow test.
Everything is a trade off...

 

I read it, but that does not compare apples to apples. It should be noted that is not a test of a CAI with a conical filter. That is a test of a stock replacement air filter (in the case of Ford gas engines, this is the flat rectangular one that replaces your OEM - same style on the Duramax).

There is a significant design difference between the stock filters and the K&N conical filters used in their cold air intake systems and I have not seen the same test done with one of these - I believe that would be interesting to see as perhaps there are better filters out there. I would then likely buy the K&N Aircharger cold air intake system and just replace the conical filter at the intake end with a superior filter.


Additional info pertaining to first post:
K&N Model # is 63-2570
Approximate price $225 - $275
Available everywhere (best to go local as you would save on shipping as long as the price is competitive)

Fuel mileage increase is negligible because you put your foot into it more often because it makes the engine more responsive.

 

I ran two types of K&N's filters on a previous truck (2000 Dodge Dakota Quad Cab w/5.9L Magnum). The first was the standard cone-shaped aftermarket/performance filter...which was part of one of their FIPK kits. The filter had been on for less than 400 miles when I pulled it the first time during an oil change. I was a bit disappointed to find oil & dust streaked through out the intake tube, across the top of the butterfly valve on the throttle body, and along the sides of throttle body's throat. I pulled everything from the throttle body forward, washed it all down with starter fluid, cleaned, dried, and re-oiled the K&N filter element, spent about two hours looking for any problems with the entire kit, and finally re-installed it all. After about 250 miles, I pulled it apart to find the same thing happening (not as much oil, but definite signs of dust). Needless to say, the FIPK got pulled off permanently at that point.

My second foray down the K&N path was with my Shaker hood. The fiberglass air box/hood scoop was built around a K&N kit for an older Dodge Ram with the same 5.9L V8. The filter was one of the older donut-shaped filters measuring 14" in diameter and 2 5/16" in height. As with the cone-shaped K&N filter, this one started showing dust trails along the contours of the base plate and top edges of the throttle body's butterfly valve. I added one of K&N's Pre-Charger filter wraps, and that helped a bit, but it never filtered as well as the OEM system.

In the end, I found another compatible filter element (believe it was designed for an older Ford F100), and stuck with the replaceable filter media for the remaining time that I had the truck....and with much better results.


Your milage may vary, but I have had the K&N experience....and do not plan on ever using another of their air filtering solutions.

 

I have read where the big boys,,racing folks who own dyno's have put them to the test and have reported no real HP gains. Think about it a stock air filter will flow more air than a stock engine will ever use. If you take the darn thing right off you should make HP right? Lotsa flow there. Nope. Why don't they guarantee hp gains in writing that would be simple because each identical truck would have the same gains apprx.
They don't cause there are no gains just marketing hype. Now if you had a drag racer well maybe a K&N would help, lotsa flow needed.

I dont believe there is any gain also with just a after market filter change.I went with the volant(box type CAI)kit.Because of the box design of drawing air from outside of the engine compartment.I also cut the plastic header panel and by the grill for a path directly to the intake.I cant say it made much difference in HP that I can feel.But I did gain 1.5 in mpg.
